    /**
      An instance of `Ember.Application` is the starting point for every Ember
      application. It helps to instantiate, initialize and coordinate the many
      objects that make up your app.

      Each Ember app has one and only one `Ember.Application` object. In fact, the
      very first thing you should do in your application is create the instance:

      ```javascript
      window.App = Ember.Application.create();
      ```

      Typically, the application object is the only global variable. All other
      classes in your app should be properties on the `Ember.Application` instance,
      which highlights its first role: a global namespace.

      For example, if you define a view class, it might look like this:

      ```javascript
      App.MyView = Ember.View.extend();
      ```

      By default, calling `Ember.Application.create()` will automatically initialize
      your application by calling the `Ember.Application.initialize()` method. If
      you need to delay initialization, you can call your app's `deferReadiness()`
      method. When you are ready for your app to be initialized, call its
      `advanceReadiness()` method.

      You can define a `ready` method on the `Ember.Application` instance, which
      will be run by Ember when the application is initialized.

      Because `Ember.Application` inherits from `Ember.Namespace`, any classes
      you create will have useful string representations when calling `toString()`.
      See the `Ember.Namespace` documentation for more information.

      While you can think of your `Ember.Application` as a container that holds the
      other classes in your application, there are several other responsibilities
      going on under-the-hood that you may want to understand.

      ### Event Delegation

      Ember uses a technique called _event delegation_. This allows the framework
      to set up a global, shared event listener instead of requiring each view to
      do it manually. For example, instead of each view registering its own
      `mousedown` listener on its associated element, Ember sets up a `mousedown`
      listener on the `body`.

      If a `mousedown` event occurs, Ember will look at the target of the event and
      start walking up the DOM node tree, finding corresponding views and invoking
      their `mouseDown` method as it goes.

      `Ember.Application` has a number of default events that it listens for, as
      well as a mapping from lowercase events to camel-cased view method names. For
      example, the `keypress` event causes the `keyPress` method on the view to be
      called, the `dblclick` event causes `doubleClick` to be called, and so on.

      If there is a bubbling browser event that Ember does not listen for by
      default, you can specify custom events and their corresponding view method
      names by setting the application's `customEvents` property:

      ```javascript
      App = Ember.Application.create({
        customEvents: {
          // add support for the paste event
          paste: "paste"
        }
      });
      ```

      By default, the application sets up these event listeners on the document
      body. However, in cases where you are embedding an Ember application inside
      an existing page, you may want it to set up the listeners on an element
      inside the body.

      For example, if only events inside a DOM element with the ID of `ember-app`
      should be delegated, set your application's `rootElement` property:

      ```javascript
      window.App = Ember.Application.create({
        rootElement: '#ember-app'
      });
      ```

      The `rootElement` can be either a DOM element or a jQuery-compatible selector
      string. Note that *views appended to the DOM outside the root element will
      not receive events.* If you specify a custom root element, make sure you only
      append views inside it!

      To learn more about the advantages of event delegation and the Ember view
      layer, and a list of the event listeners that are setup by default, visit the
      [Ember View Layer guide](http://emberjs.com/guides/understanding-ember/the-view-layer/#toc_event-delegation).

      ### Initializers

      Libraries on top of Ember can add initializers, like so:

      ```javascript
      Ember.Application.initializer({
        name: 'api-adapter',

        initialize: function(container, application) {
          application.register('api-adapter:main', ApiAdapter);
        }
      });
      ```

      Initializers provide an opportunity to access the container, which
      organizes the different components of an Ember application. Additionally
      they provide a chance to access the instantiated application. Beyond
      being used for libraries, initializers are also a great way to organize
      dependency injection or setup in your own application.

      ### Routing

      In addition to creating your application's router, `Ember.Application` is
      also responsible for telling the router when to start routing. Transitions
      between routes can be logged with the `LOG_TRANSITIONS` flag, and more
      detailed intra-transition logging can be logged with
      the `LOG_TRANSITIONS_INTERNAL` flag:

      ```javascript
      window.App = Ember.Application.create({
        LOG_TRANSITIONS: true, // basic logging of successful transitions
        LOG_TRANSITIONS_INTERNAL: true // detailed logging of all routing steps
      });
      ```

      By default, the router will begin trying to translate the current URL into
      application state once the browser emits the `DOMContentReady` event. If you
      need to defer routing, you can call the application's `deferReadiness()`
      method. Once routing can begin, call the `advanceReadiness()` method.

      If there is any setup required before routing begins, you can implement a
      `ready()` method on your app that will be invoked immediately before routing
      begins.
      ```

      @class Application
      @namespace Ember
      @extends Ember.Namespace
    */

    var Application = Namespace.extend(DeferredMixin, {
      _suppressDeferredDeprecation: true,

      /**
        The root DOM element of the Application. This can be specified as an
        element or a
        [jQuery-compatible selector string](http://api.jquery.com/category/selectors/).

        This is the element that will be passed to the Application's,
        `eventDispatcher`, which sets up the listeners for event delegation. Every
        view in your application should be a child of the element you specify here.

        @property rootElement
        @type DOMElement

      */
      rootElement: 'body',

      /**

        The event dispatcher is created by the application at initialization time
        and sets up event listeners on the DOM element described by the
        application's `rootElement` property.

        See the documentation for `Ember.EventDispatcher` for more information.

        @property eventDispatcher
        @type Ember.EventDispatcher
        @default null
      */
      eventDispatcher: null,

      /**
        The DOM events for which the event dispatcher should listen.

        By default, the application's `Ember.EventDispatcher` listens
        for a set of standard DOM events, such as `mousedown` and
        `keyup`, and delegates them to your application's `Ember.View`
        instances.

        If you would like additional bubbling events to be delegated to your
        views, set your `Ember.Application`'s `customEvents` property
        to a hash containing the DOM event name as the key and the
        corresponding view method name as the value. For example:

        ```javascript
        App = Ember.Application.create({
          customEvents: {
            // add support for the paste event
            paste: "paste"
          }
        });
        ```

        @default null

          });

          var maxNameLength = Math.max.apply(this, nameLengths);

        This allows you to perform asynchronous setup logic and defer

        `App.inject`) or for service lookup. Each factory is registered with

        A simple example:

        ```javascript
        var App = Ember.Application.create();
        App.Orange  = Ember.Object.extend();
        App.register('fruit:favorite', App.Orange);
        ```

        Ember will resolve factories from the `App` namespace automatically.
        For example `App.CarsController` will be discovered and returned if
        an application requests `controller:cars`.

        An example of registering a controller with a non-standard name:

        ```javascript
        var App = Ember.Application.create(),
            Session  = Ember.Controller.extend();

        App.register('controller:session', Session);

        // The Session controller can now be treated like a normal controller,
        // despite its non-standard name.
        App.ApplicationController = Ember.Controller.extend({
          needs: ['session']
        });
        ```

        Registered factories are **instantiated** by having `create`
        called on them. Additionally they are **singletons**, each time
        they are looked up they return the same instance.

        Some examples modifying that default behavior:

        ```javascript
        var App = Ember.Application.create();

        App.Person  = Ember.Object.extend();
        App.Orange  = Ember.Object.extend();
        App.Email   = Ember.Object.extend();
        App.session = Ember.Object.create();

        App.register('model:user', App.Person, {singleton: false });
        App.register('fruit:favorite', App.Orange);
        App.register('communication:main', App.Email, {singleton: false});
        App.register('session', App.session, {instantiate: false});
        ```

        @method register
        @param  fullName {String} type:name (e.g., 'model:user')
        @param  factory {Function} (e.g., App.Person)
        @param  options {Object} (optional) disable instantiation or singleton usage
      **/
      register: function() {
        var container = this.__container__;
        container.register.apply(container, arguments);
      },

      /**
        Define a dependency injection onto a specific factory or all factories
        of a type.

        When Ember instantiates a controller, view, or other framework component
        it can attach a dependency to that component. This is often used to
        provide services to a set of framework components.

        An example of providing a session object to all controllers:

        ```javascript
        var App = Ember.Application.create(),
            Session = Ember.Object.extend({ isAuthenticated: false });

        // A factory must be registered before it can be injected
        App.register('session:main', Session);

        // Inject 'session:main' onto all factories of the type 'controller'
        // with the name 'session'
        App.inject('controller', 'session', 'session:main');

        App.IndexController = Ember.Controller.extend({
          isLoggedIn: Ember.computed.alias('session.isAuthenticated')
        });
        ```

        Injections can also be performed on specific factories.

        ```javascript
        App.inject(<full_name or type>, <property name>, <full_name>)
        App.inject('route', 'source', 'source:main')
        App.inject('route:application', 'email', 'model:email')
        ```

        It is important to note that injections can only be performed on
        classes that are instantiated by Ember itself. Instantiating a class
        directly (via `create` or `new`) bypasses the dependency injection
        system.

        Ember-Data instantiates its models in a unique manner, and consequently
        injections onto models (or all models) will not work as expected. Injections
        on models can be enabled by setting `Ember.MODEL_FACTORY_INJECTIONS`
        to `true`.

        @method inject
        @param  factoryNameOrType {String}
        @param  property {String}

        2. Destroy all objects in the container
        3. Create a new application container
        4. Re-route to the existing url

        Typical Example:

        ```javascript

        var App;

        run(function() {
          App = Ember.Application.create();
        });

        module("acceptance test", {
          setup: function() {
            App.reset();
          }
        });

        test("first test", function() {
          // App is freshly reset
        });

        test("first test", function() {
          // App is again freshly reset
        });
        ```

        Advanced Example:

        Occasionally you may want to prevent the app from initializing during
        setup. This could enable extra configuration, or enable asserting prior
        to the app becoming ready.

        ```javascript

        var App;

        run(function() {
          App = Ember.Application.create();
        });

        module("acceptance test", {
          setup: function() {
            run(function() {
              App.reset();
              App.deferReadiness();
            });
          }
        });

        test("first test", function() {
          ok(true, 'something before app is initialized');

          run(function() {
            App.advanceReadiness();
          });
          ok(true, 'something after app is initialized');
        });

        Initializer receives an object which has the following attributes:
        `name`, `before`, `after`, `initialize`. The only required attribute is
        `initialize, all others are optional.

        * `name` allows you to specify under which name the initializer is registered.
        This must be a unique name, as trying to register two initializers with the
        same name will result in an error.

        ```javascript
        Ember.Application.initializer({
          name: 'namedInitializer',
          initialize: function(container, application) {
            Ember.debug("Running namedInitializer!");
          }
        });
        ```

        * `before` and `after` are used to ensure that this initializer is ran prior
        or after the one identified by the value. This value can be a single string
        or an array of strings, referencing the `name` of other initializers.

        An example of ordering initializers, we create an initializer named `first`:

        ```javascript
        Ember.Application.initializer({
          name: 'first',
          initialize: function(container, application) {
            Ember.debug("First initializer!");
          }
        });

        // DEBUG: First initializer!
        ```

        We add another initializer named `second`, specifying that it should run
        after the initializer named `first`:

        ```javascript
        Ember.Application.initializer({
          name: 'second',
          after: 'first',

          initialize: function(container, application) {
            Ember.debug("Second initializer!");
          }
        });

        // DEBUG: First initializer!
        // DEBUG: Second initializer!
        ```

        Afterwards we add a further initializer named `pre`, this time specifying
        that it should run before the initializer named `first`:

        ```javascript
        Ember.Application.initializer({
          name: 'pre',
          before: 'first',

          initialize: function(container, application) {
            Ember.debug("Pre initializer!");
          }
        });

        // DEBUG: Pre initializer!
        // DEBUG: First initializer!
        // DEBUG: Second initializer!
        ```

        Finally we add an initializer named `post`, specifying it should run after
        both the `first` and the `second` initializers:

        ```javascript
        Ember.Application.initializer({
          name: 'post',
          after: ['first', 'second'],

          initialize: function(container, application) {
            Ember.debug("Post initializer!");
          }
        });

        // DEBUG: Pre initializer!
        // DEBUG: First initializer!
        // DEBUG: Second initializer!
        // DEBUG: Post initializer!
        ```

        * `initialize` is a callback function that receives two arguments, `container`
        and `application` on which you can operate.

        Example of using `container` to preload data into the store:

        ```javascript
        Ember.Application.initializer({
          name: "preload-data",

          initialize: function(container, application) {
            var store = container.lookup('store:main');
            store.pushPayload(preloadedData);
          }
        });
        ```

        Example of using `application` to register an adapter:

        ```javascript
        Ember.Application.initializer({
          name: 'api-adapter',

          initialize: function(container, application) {
            application.register('api-adapter:main', ApiAdapter);
          }
        });
        ```

        @param initializer {Object}
       */
      initializer: function(initializer) {
        // If this is the first initializer being added to a subclass, we are going to reopen the class
        // to make sure we have a new `initializers` object, which extends from the parent class' using
        // prototypal inheritance. Without this, attempting to add initializers to the subclass would
        // pollute the parent class as well as other subclasses.
        if (this.superclass.initializers !== undefined && this.superclass.initializers === this.initializers) {
          this.reopenClass({
            initializers: create(this.initializers)
          });

        Ember.assert("An initializer cannot be registered without an initialize function", canInvoke(initializer, 'initialize'));

    /**
      The DefaultResolver defines the default lookup rules to resolve
      container lookups before consulting the container for registered
      items:

      * templates are looked up on `Ember.TEMPLATES`
      * other names are looked up on the application after converting
        the name. For example, `controller:post` looks up
        `App.PostController` by default.
      * there are some nuances (see examples below)

      ### How Resolving Works

      The container calls this object's `resolve` method with the
      `fullName` argument.

      It first parses the fullName into an object using `parseName`.

      Then it checks for the presence of a type-specific instance
      method of the form `resolve[Type]` and calls it if it exists.
      For example if it was resolving 'template:post', it would call
      the `resolveTemplate` method.

      Its last resort is to call the `resolveOther` method.

      The methods of this object are designed to be easy to override
      in a subclass. For example, you could enhance how a template
      is resolved like so:

      ```javascript
      App = Ember.Application.create({
        Resolver: Ember.DefaultResolver.extend({
          resolveTemplate: function(parsedName) {
            var resolvedTemplate = this._super(parsedName);
            if (resolvedTemplate) { return resolvedTemplate; }
            return Ember.TEMPLATES['not_found'];
          }
        })
      });
      ```

      Some examples of how names are resolved:

      ```
      'template:post' //=> Ember.TEMPLATES['post']
      'template:posts/byline' //=> Ember.TEMPLATES['posts/byline']
      'template:posts.byline' //=> Ember.TEMPLATES['posts/byline']
      'template:blogPost' //=> Ember.TEMPLATES['blogPost']
                          //   OR
                          //   Ember.TEMPLATES['blog_post']
      'controller:post' //=> App.PostController
      'controller:posts.index' //=> App.PostsIndexController
      'controller:blog/post' //=> Blog.PostController
      'controller:basic' //=> Ember.Controller
      'route:post' //=> App.PostRoute
      'route:posts.index' //=> App.PostsIndexRoute
      'route:blog/post' //=> Blog.PostRoute
      'route:basic' //=> Ember.Route
      'view:post' //=> App.PostView
      'view:posts.index' //=> App.PostsIndexView
      'view:blog/post' //=> Blog.PostView
      'view:basic' //=> Ember.View
      'foo:post' //=> App.PostFoo
      'model:post' //=> App.Post

      ```javascript
      Ember.Handlebars.helper('capitalize', function(value) {
        return value.toUpperCase();
      });
      ```

      The above bound helper can be used inside of templates as follows:

      ```handlebars
      {{capitalize name}}
      ```

      In this case, when the `name` property of the template's context changes,
      the rendered value of the helper will update to reflect this change.

      For more examples of bound helpers, see documentation for
      `Ember.Handlebars.registerBoundHelper`.

      ## Custom view helper example

      Assuming a view subclass named `App.CalendarView` were defined, a helper
      for rendering instances of this view could be registered as follows:

      ```javascript
      Ember.Handlebars.helper('calendar', App.CalendarView):
      ```

      The above bound helper can be used inside of templates as follows:

      ```handlebars
      {{calendar}}
      ```

      Which is functionally equivalent to:

      ```handlebars
      {{view App.CalendarView}}
      ```

      Options in the helper will be passed to the view in exactly the same
      manner as with the `view` helper.

    /**

      The `{{input}}` helper inserts an HTML `<input>` tag into the template,
      with a `type` value of either `text` or `checkbox`. If no `type` is provided,
      `text` will be the default value applied. The attributes of `{{input}}`
      match those of the native HTML tag as closely as possible for these two types.

      ## Use as text field
      An `{{input}}` with no `type` or a `type` of `text` will render an HTML text input.
      The following HTML attributes can be set via the helper:

     <table>
      <tr><td>`readonly`</td><td>`required`</td><td>`autofocus`</td></tr>
      <tr><td>`value`</td><td>`placeholder`</td><td>`disabled`</td></tr>
      <tr><td>`size`</td><td>`tabindex`</td><td>`maxlength`</td></tr>
      <tr><td>`name`</td><td>`min`</td><td>`max`</td></tr>
      <tr><td>`pattern`</td><td>`accept`</td><td>`autocomplete`</td></tr>
      <tr><td>`autosave`</td><td>`formaction`</td><td>`formenctype`</td></tr>
      <tr><td>`formmethod`</td><td>`formnovalidate`</td><td>`formtarget`</td></tr>
      <tr><td>`height`</td><td>`inputmode`</td><td>`multiple`</td></tr>
      <tr><td>`step`</td><td>`width`</td><td>`form`</td></tr>
      <tr><td>`selectionDirection`</td><td>`spellcheck`</td><td>&nbsp;</td></tr>
     </table>


      When set to a quoted string, these values will be directly applied to the HTML
      element. When left unquoted, these values will be bound to a property on the
      template's current rendering context (most typically a controller instance).

      ## Unbound:

      ```handlebars
      {{input value="http://www.facebook.com"}}
      ```


      ```html
      <input type="text" value="http://www.facebook.com"/>
      ```

      ## Bound:

      ```javascript
      App.ApplicationController = Ember.Controller.extend({
        firstName: "Stanley",
        entryNotAllowed: true
      });
      ```


      ```handlebars
      {{input type="text" value=firstName disabled=entryNotAllowed size="50"}}
      ```


      ```html
      <input type="text" value="Stanley" disabled="disabled" size="50"/>
      ```

      ## Actions

      The helper can send multiple actions based on user events.

      The action property defines the action which is send when
      the user presses the return key.

      ```handlebars
      {{input action="submit"}}
      ```

      The helper allows some user events to send actions.

    * `enter`
    * `insert-newline`
    * `escape-press`
    * `focus-in`
    * `focus-out`
    * `key-press`

      For example, if you desire an action to be sent when the input is blurred,
      you only need to setup the action name to the event name property.

      ```handlebars
      {{input focus-in="alertMessage"}}
      ```

      See more about [Text Support Actions](/api/classes/Ember.TextField.html)

      ## Extension

      Internally, `{{input type="text"}}` creates an instance of `Ember.TextField`, passing
      arguments from the helper to `Ember.TextField`'s `create` method. You can extend the
      capabilities of text inputs in your applications by reopening this class. For example,
      if you are building a Bootstrap project where `data-*` attributes are used, you
      can add one to the `TextField`'s `attributeBindings` property:


      ```javascript
      Ember.TextField.reopen({
        attributeBindings: ['data-error']
      });
      ```

      Keep in mind when writing `Ember.TextField` subclasses that `Ember.TextField`
      itself extends `Ember.Component`, meaning that it does NOT inherit
      the `controller` of the parent view.

      See more about [Ember components](/api/classes/Ember.Component.html)


      ## Use as checkbox

      An `{{input}}` with a `type` of `checkbox` will render an HTML checkbox input.
      The following HTML attributes can be set via the helper:

    * `checked`
    * `disabled`
    * `tabindex`
    * `indeterminate`
    * `name`
    * `autofocus`
    * `form`


      When set to a quoted string, these values will be directly applied to the HTML
      element. When left unquoted, these values will be bound to a property on the
      template's current rendering context (most typically a controller instance).

      ## Unbound:

      ```handlebars
      {{input type="checkbox" name="isAdmin"}}
      ```

      ```html
      <input type="checkbox" name="isAdmin" />
      ```

      ## Bound:

      ```javascript
      App.ApplicationController = Ember.Controller.extend({
        isAdmin: true
      });
      ```


      ```handlebars
      {{input type="checkbox" checked=isAdmin }}
      ```


      ```html
      <input type="checkbox" checked="checked" />
      ```

      ## Extension

      Internally, `{{input type="checkbox"}}` creates an instance of `Ember.Checkbox`, passing
      arguments from the helper to `Ember.Checkbox`'s `create` method. You can extend the
      capablilties of checkbox inputs in your applications by reopening this class. For example,
      if you wanted to add a css class to all checkboxes in your application:


      ```javascript
      Ember.Checkbox.reopen({
        classNames: ['my-app-checkbox']
      });
      ```


      @method input
      @for Ember.Handlebars.helpers
      @param {Hash} options
    */
    function inputHelper(options) {
      Ember.assert('You can only pass attributes to the `input` helper, not arguments', arguments.length < 2);

      var hash = options.hash,
          types = options.hashTypes,
          inputType = _resolveOption(this, options, 'type'),
          onEvent = hash.on;

      if (inputType === 'checkbox') {
        delete hash.type;
        delete types.type;

        Ember.assert("{{input type='checkbox'}} does not support setting `value=someBooleanValue`; you must use `checked=someBooleanValue` instead.", options.hashTypes.value !== 'ID');

        return helpers.view.call(this, Checkbox, options);
      } else {
        delete hash.on;

        hash.onEvent = onEvent || 'enter';
        return helpers.view.call(this, TextField, options);
      }
    }

    __exports__.inputHelper = inputHelper;/**
      `{{textarea}}` inserts a new instance of `<textarea>` tag into the template.
      The attributes of `{{textarea}}` match those of the native HTML tags as
      closely as possible.

      The following HTML attributes can be set:

        * `value`
        * `name`
        * `rows`
        * `cols`
        * `placeholder`
        * `disabled`
        * `maxlength`
        * `tabindex`
        * `selectionEnd`
        * `selectionStart`
        * `selectionDirection`
        * `wrap`
        * `readonly`
        * `autofocus`
        * `form`
        * `spellcheck`
        * `required`

      When set to a quoted string, these value will be directly applied to the HTML
      element. When left unquoted, these values will be bound to a property on the
      template's current rendering context (most typically a controller instance).

      Unbound:

      ```handlebars
      {{textarea value="Lots of static text that ISN'T bound"}}
      ```

      Would result in the following HTML:

      ```html
      <textarea class="ember-text-area">
        Lots of static text that ISN'T bound
      </textarea>
      ```

      Bound:

      In the following example, the `writtenWords` property on `App.ApplicationController`
      will be updated live as the user types 'Lots of text that IS bound' into
      the text area of their browser's window.

      ```javascript
      App.ApplicationController = Ember.Controller.extend({
        writtenWords: "Lots of text that IS bound"
      });
      ```

      ```handlebars
      {{textarea value=writtenWords}}
      ```

       Would result in the following HTML:

      ```html
      <textarea class="ember-text-area">
        Lots of text that IS bound
      </textarea>
      ```

      If you wanted a one way binding between the text area and a div tag
      somewhere else on your screen, you could use `Ember.computed.oneWay`:

      ```javascript
      App.ApplicationController = Ember.Controller.extend({
        writtenWords: "Lots of text that IS bound",
        outputWrittenWords: Ember.computed.oneWay("writtenWords")
      });
      ```

      ```handlebars
      {{textarea value=writtenWords}}

      <div>
        {{outputWrittenWords}}
      </div>
      ```

      Would result in the following HTML:

      ```html
      <textarea class="ember-text-area">
        Lots of text that IS bound
      </textarea>

      <-- the following div will be updated in real time as you type -->

      <div>
        Lots of text that IS bound
      </div>
      ```

      Finally, this example really shows the power and ease of Ember when two
      properties are bound to eachother via `Ember.computed.alias`. Type into
      either text area box and they'll both stay in sync. Note that
      `Ember.computed.alias` costs more in terms of performance, so only use it when
      your really binding in both directions:

      ```javascript
      App.ApplicationController = Ember.Controller.extend({
        writtenWords: "Lots of text that IS bound",
        twoWayWrittenWords: Ember.computed.alias("writtenWords")
      });
      ```

      ```handlebars
      {{textarea value=writtenWords}}
      {{textarea value=twoWayWrittenWords}}
      ```

      ```html
      <textarea id="ember1" class="ember-text-area">
        Lots of text that IS bound
      </textarea>

      <-- both updated in real time -->

      <textarea id="ember2" class="ember-text-area">
        Lots of text that IS bound
      </textarea>
      ```

      ## Actions

      The helper can send multiple actions based on user events.

      The action property defines the action which is send when
      the user presses the return key.

      ```handlebars
      {{input action="submit"}}
      ```

      The helper allows some user events to send actions.

    * `enter`
    * `insert-newline`
    * `escape-press`
    * `focus-in`
    * `focus-out`
    * `key-press`

      For example, if you desire an action to be sent when the input is blurred,
      you only need to setup the action name to the event name property.

      ```handlebars
      {{textarea focus-in="alertMessage"}}
      ```

      See more about [Text Support Actions](/api/classes/Ember.TextArea.html)

      ## Extension

      Internally, `{{textarea}}` creates an instance of `Ember.TextArea`, passing
      arguments from the helper to `Ember.TextArea`'s `create` method. You can
      extend the capabilities of text areas in your application by reopening this
      class. For example, if you are building a Bootstrap project where `data-*` 
      attributes are used, you can globally add support for a `data-*` attribute
      on all `{{textarea}}`s' in your app by reopening `Ember.TextArea` or
      `Ember.TextSupport` and adding it to the `attributeBindings` concatenated
      property:

      ```javascript
      Ember.TextArea.reopen({
        attributeBindings: ['data-error']
      });
      ```

      Keep in mind when writing `Ember.TextArea` subclasses that `Ember.TextArea`
      itself extends `Ember.Component`, meaning that it does NOT inherit

      ## Direct manipulation of `checked`

      The `checked` attribute of an `Ember.Checkbox` object should always be set
      through the Ember object or by interacting with its rendered element
      representation via the mouse, keyboard, or touch. Updating the value of the
      checkbox via jQuery will result in the checked value of the object and its
      element losing synchronization.

      Because HTML `input` elements are self closing `layout` and `layoutName`
      properties will not be applied. See [Ember.View](/api/classes/Ember.View.html)'s

    /**
      The `Ember.Select` view class renders a
      [select](https://developer.mozilla.org/en/HTML/Element/select) HTML element,
      allowing the user to choose from a list of options.

      The text and `value` property of each `<option>` element within the
      `<select>` element are populated from the objects in the `Element.Select`'s
      `content` property. The underlying data object of the selected `<option>` is
      stored in the `Element.Select`'s `value` property.

      ## The Content Property (array of strings)

      The simplest version of an `Ember.Select` takes an array of strings as its
      `content` property. The string will be used as both the `value` property and
      the inner text of each `<option>` element inside the rendered `<select>`.

      Example:

      ```javascript
      App.ApplicationController = Ember.ObjectController.extend({
        names: ["Yehuda", "Tom"]
      });
      ```

      ```handlebars
      {{view Ember.Select content=names}}
      ```

      Would result in the following HTML:

      ```html
      <select class="ember-select">
        <option value="Yehuda">Yehuda</option>
        <option value="Tom">Tom</option>
      </select>
      ```

      You can control which `<option>` is selected through the `Ember.Select`'s
      `value` property:

      ```javascript
      App.ApplicationController = Ember.ObjectController.extend({
        selectedName: 'Tom',
        names: ["Yehuda", "Tom"]
      });
      ```

      ```handlebars
      {{view Ember.Select
             content=names
             value=selectedName
      }}
      ```

      Would result in the following HTML with the `<option>` for 'Tom' selected:

      ```html
      <select class="ember-select">
        <option value="Yehuda">Yehuda</option>
        <option value="Tom" selected="selected">Tom</option>
      </select>
      ```

      A user interacting with the rendered `<select>` to choose "Yehuda" would
      update the value of `selectedName` to "Yehuda".

      ## The Content Property (array of Objects)

      An `Ember.Select` can also take an array of JavaScript or Ember objects as
      its `content` property.

      When using objects you need to tell the `Ember.Select` which property should
      be accessed on each object to supply the `value` attribute of the `<option>`
      and which property should be used to supply the element text.

      The `optionValuePath` option is used to specify the path on each object to
      the desired property for the `value` attribute. The `optionLabelPath`
      specifies the path on each object to the desired property for the
      element's text. Both paths must reference each object itself as `content`:

      ```javascript
      App.ApplicationController = Ember.ObjectController.extend({
        programmers: [
          {firstName: "Yehuda", id: 1},
          {firstName: "Tom",    id: 2}
        ]
      });
      ```

      ```handlebars
      {{view Ember.Select
             content=programmers
             optionValuePath="content.id"
             optionLabelPath="content.firstName"}}
      ```

      Would result in the following HTML:

      ```html
      <select class="ember-select">
        <option value="1">Yehuda</option>
        <option value="2">Tom</option>
      </select>
      ```

      The `value` attribute of the selected `<option>` within an `Ember.Select`
      can be bound to a property on another object:

      ```javascript
      App.ApplicationController = Ember.ObjectController.extend({
        programmers: [
          {firstName: "Yehuda", id: 1},
          {firstName: "Tom",    id: 2}
        ],
        currentProgrammer: {
          id: 2
        }
      });
      ```

      ```handlebars
      {{view Ember.Select
             content=programmers
             optionValuePath="content.id"
             optionLabelPath="content.firstName"
             value=currentProgrammer.id}}
      ```

      Would result in the following HTML with a selected option:

      ```html
      <select class="ember-select">
        <option value="1">Yehuda</option>
        <option value="2" selected="selected">Tom</option>
      </select>
      ```

      Interacting with the rendered element by selecting the first option
      ('Yehuda') will update the `id` of `currentProgrammer`
      to match the `value` property of the newly selected `<option>`.

      Alternatively, you can control selection through the underlying objects
      used to render each object by binding the `selection` option. When the selected
      `<option>` is changed, the property path provided to `selection`
      will be updated to match the content object of the rendered `<option>`
      element:

      ```javascript

      var yehuda = {firstName: "Yehuda", id: 1, bff4eva: 'tom'}
      var tom = {firstName: "Tom", id: 2, bff4eva: 'yehuda'};

      App.ApplicationController = Ember.ObjectController.extend({
        selectedPerson: tom,
        programmers: [
          yehuda,
          tom
        ]
      });
      ```

      ```handlebars
      {{view Ember.Select
             content=programmers
             optionValuePath="content.id"
             optionLabelPath="content.firstName"
             selection=selectedPerson}}
      ```

      Would result in the following HTML with a selected option:

      ```html
      <select class="ember-select">
        <option value="1">Yehuda</option>
        <option value="2" selected="selected">Tom</option>
      </select>
      ```

      Interacting with the rendered element by selecting the first option
      ('Yehuda') will update the `selectedPerson` to match the object of
      the newly selected `<option>`. In this case it is the first object
      in the `programmers`

      ## Supplying a Prompt

      A `null` value for the `Ember.Select`'s `value` or `selection` property
      results in there being no `<option>` with a `selected` attribute:

      ```javascript
      App.ApplicationController = Ember.ObjectController.extend({
        selectedProgrammer: null,
        programmers: [
          "Yehuda",
          "Tom"
        ]
      });
      ```

      ``` handlebars
      {{view Ember.Select
             content=programmers
             value=selectedProgrammer
      }}
      ```

      Would result in the following HTML:

      ```html
      <select class="ember-select">
        <option value="Yehuda">Yehuda</option>
        <option value="Tom">Tom</option>
      </select>
      ```

      Although `selectedProgrammer` is `null` and no `<option>`
      has a `selected` attribute the rendered HTML will display the
      first item as though it were selected. You can supply a string
      value for the `Ember.Select` to display when there is no selection
      with the `prompt` option:

      ```javascript
      App.ApplicationController = Ember.ObjectController.extend({
        selectedProgrammer: null,
        programmers: [
          "Yehuda",
          "Tom"
        ]
      });
      ```

      ```handlebars
      {{view Ember.Select
             content=programmers
             value=selectedProgrammer
             prompt="Please select a name"
      }}
      ```

      Would result in the following HTML:

      ```html
      <select class="ember-select">
        <option>Please select a name</option>
        <option value="Yehuda">Yehuda</option>
        <option value="Tom">Tom</option>
      </select>
      ```

      Register a bound handlebars helper. Bound helpers behave similarly to regular
      handlebars helpers, with the added ability to re-render when the underlying data
      changes.

      ## Simple example

      ```javascript
      Ember.Handlebars.registerBoundHelper('capitalize', function(value) {
        return Ember.String.capitalize(value);
      });
      ```

      The above bound helper can be used inside of templates as follows:

      ```handlebars
      {{capitalize name}}
      ```

      In this case, when the `name` property of the template's context changes,
      the rendered value of the helper will update to reflect this change.

      ## Example with options

      Like normal handlebars helpers, bound helpers have access to the options
      passed into the helper call.

      ```javascript
      Ember.Handlebars.registerBoundHelper('repeat', function(value, options) {
        var count = options.hash.count;
        var a = [];
        while(a.length < count) {
            a.push(value);
        }
        return a.join('');
      });
      ```

      This helper could be used in a template as follows:

      ```handlebars
      {{repeat text count=3}}
      ```

      ## Example with bound options

      Bound hash options are also supported. Example:

      ```handlebars
      {{repeat text count=numRepeats}}
      ```

      In this example, count will be bound to the value of
      the `numRepeats` property on the context. If that property
      changes, the helper will be re-rendered.

      ## Example with extra dependencies

      The `Ember.Handlebars.registerBoundHelper` method takes a variable length
      third parameter which indicates extra dependencies on the passed in value.
      This allows the handlebars helper to update when these dependencies change.

      ```javascript
      Ember.Handlebars.registerBoundHelper('capitalizeName', function(value) {
        return value.get('name').toUpperCase();
      }, 'name');
      ```

      ## Example with multiple bound properties

      `Ember.Handlebars.registerBoundHelper` supports binding to
      multiple properties, e.g.:

      ```javascript
      Ember.Handlebars.registerBoundHelper('concatenate', function() {
        var values = Array.prototype.slice.call(arguments, 0, -1);
        return values.join('||');
      });
      ```

      Which allows for template syntax such as `{{concatenate prop1 prop2}}` or
      `{{concatenate prop1 prop2 prop3}}`. If any of the properties change,
      the helper will re-render.  Note that dependency keys cannot be
      using in conjunction with multi-property helpers, since it is ambiguous
      which property the dependent keys would belong to.

      ## Use with unbound helper

      The `{{unbound}}` helper can be used with bound helper invocations
      to render them in their unbound form, e.g.

      ```handlebars
      {{unbound capitalize name}}
      ```

      In this example, if the name property changes, the helper
      will not re-render.

      ## Use with blocks not supported

      Bound helpers do not support use with Handlebars blocks or
      the addition of child views of any kind.

      @method registerBoundHelper
      @for Ember.Handlebars
      @param {String} name
      @param {Function} function
      @param {String} dependentKeys*
    */
    function registerBoundHelper(name, fn) {
      var boundHelperArgs = slice.call(arguments, 1),
          boundFn = makeBoundHelper.apply(this, boundHelperArgs);
      EmberHandlebars.registerHelper(name, boundFn);
    }

    __exports__.registerBoundHelper = registerBoundHelper;/**
      A helper function used by `registerBoundHelper`. Takes the
      provided Handlebars helper function fn and returns it in wrapped
      bound helper form.

      The main use case for using this outside of `registerBoundHelper`
      is for registering helpers on the container:

      ```js
      var boundHelperFn = Ember.Handlebars.makeBoundHelper(function(word) {
        return word.toUpperCase();
      });

      container.register('helper:my-bound-helper', boundHelperFn);
      ```

      In the above example, if the helper function hadn't been wrapped in
      `makeBoundHelper`, the registered helper would be unbound.

      @for Ember.Handlebars

      function helper() {
        var properties = slice.call(arguments, 0, -1),

          template = fn.fn,
          inverse = fn.inverse,
          normalized, propertyValue, result;

      normalized = normalizePath(context, property, data);

    /**
      Use the `{{with}}` helper when you want to scope context. Take the following code as an example:

      ```handlebars
      <h5>{{user.name}}</h5>

      <div class="role">
        <h6>{{user.role.label}}</h6>
        <span class="role-id">{{user.role.id}}</span>

        <p class="role-desc">{{user.role.description}}</p>
      </div>
      ```

      `{{with}}` can be our best friend in these cases,
      instead of writing `user.role.*` over and over, we use `{{#with user.role}}`.
      Now the context within the `{{#with}} .. {{/with}}` block is `user.role` so you can do the following:

      ```handlebars
      <h5>{{user.name}}</h5>

      <div class="role">
        {{#with user.role}}
          <h6>{{label}}</h6>
          <span class="role-id">{{id}}</span>

          <p class="role-desc">{{description}}</p>
        {{/with}}
      </div>
      ```

      ### `as` operator

      This operator aliases the scope to a new name. It's helpful for semantic clarity and to retain
      default scope or to reference from another `{{with}}` block.

      ```handlebars
      // posts might not be
      {{#with user.posts as blogPosts}}
        <div class="notice">
          There are {{blogPosts.length}} blog posts written by {{user.name}}.
        </div>

        {{#each post in blogPosts}}
          <li>{{post.title}}</li>
        {{/each}}
      {{/with}}
      ```

      Without the `as` operator, it would be impossible to reference `user.name` in the example above.

      NOTE: The alias should not reuse a name from the bound property path.
      For example: `{{#with foo.bar as foo}}` is not supported because it attempts to alias using
      the first part of the property path, `foo`. Instead, use `{{#with foo.bar as baz}}`.

      ### `controller` option

      Adding `controller='something'` instructs the `{{with}}` helper to create and use an instance of
      the specified controller with the new context as its content.

      This is very similar to using an `itemController` option with the `{{each}}` helper.

      ```handlebars
      {{#with users.posts controller='userBlogPosts'}}
        {{!- The current context is wrapped in our controller instance }}
      {{/with}}
      ```

      In the above example, the template provided to the `{{with}}` block is now wrapped in the
      `userBlogPost` controller, which provides a very elegant way to decorate the context with custom
      functions/properties.

    /**
      `bind-attr` allows you to create a binding between DOM element attributes and
      Ember objects. For example:

      ```handlebars
      <img {{bind-attr src="imageUrl" alt="imageTitle"}}>
      ```

      The above handlebars template will fill the `<img>`'s `src` attribute with
      the value of the property referenced with `"imageUrl"` and its `alt`
      attribute with the value of the property referenced with `"imageTitle"`.

      If the rendering context of this template is the following object:

      ```javascript
      {
        imageUrl: 'http://lolcats.info/haz-a-funny',
        imageTitle: 'A humorous image of a cat'
      }
      ```

      The resulting HTML output will be:

      ```html
      <img src="http://lolcats.info/haz-a-funny" alt="A humorous image of a cat">
      ```

      `bind-attr` cannot redeclare existing DOM element attributes. The use of `src`
      in the following `bind-attr` example will be ignored and the hard coded value
      of `src="/failwhale.gif"` will take precedence:

      ```handlebars
      <img src="/failwhale.gif" {{bind-attr src="imageUrl" alt="imageTitle"}}>
      ```

      ### `bind-attr` and the `class` attribute

      `bind-attr` supports a special syntax for handling a number of cases unique
      to the `class` DOM element attribute. The `class` attribute combines
      multiple discrete values into a single attribute as a space-delimited
      list of strings. Each string can be:

      * a string return value of an object's property.
      * a boolean return value of an object's property
      * a hard-coded value

      A string return value works identically to other uses of `bind-attr`. The
      return value of the property will become the value of the attribute. For
      example, the following view and template:

      ```javascript
        AView = View.extend({
          someProperty: function() {
            return "aValue";
          }.property()
        })
      ```

      ```handlebars
      <img {{bind-attr class="view.someProperty}}>
      ```

      Result in the following rendered output:

      ```html
      <img class="aValue">
      ```

      A boolean return value will insert a specified class name if the property
      returns `true` and remove the class name if the property returns `false`.

      A class name is provided via the syntax
      `somePropertyName:class-name-if-true`.

      ```javascript
      AView = View.extend({
        someBool: true
      })
      ```

      ```handlebars
      <img {{bind-attr class="view.someBool:class-name-if-true"}}>
      ```

      Result in the following rendered output:

      ```html
      <img class="class-name-if-true">
      ```

      An additional section of the binding can be provided if you want to
      replace the existing class instead of removing it when the boolean
      value changes:

      ```handlebars
      <img {{bind-attr class="view.someBool:class-name-if-true:class-name-if-false"}}>
      ```

      A hard-coded value can be used by prepending `:` to the desired
      class name: `:class-name-to-always-apply`.

      ```handlebars
      <img {{bind-attr class=":class-name-to-always-apply"}}>
      ```

      Results in the following rendered output:

      ```html
      <img class="class-name-to-always-apply">
      ```

      All three strategies - string return value, boolean return value, and
      hard-coded value – can be combined in a single declaration:

      ```handlebars
      <img {{bind-attr class=":class-name-to-always-apply view.someBool:class-name-if-true view.someProperty"}}>
      ```

    /**
      `{{collection}}` is a `Ember.Handlebars` helper for adding instances of
      `Ember.CollectionView` to a template. See [Ember.CollectionView](/api/classes/Ember.CollectionView.html)
       for additional information on how a `CollectionView` functions.

      `{{collection}}`'s primary use is as a block helper with a `contentBinding`
      option pointing towards an `Ember.Array`-compatible object. An `Ember.View`
      instance will be created for each item in its `content` property. Each view
      will have its own `content` property set to the appropriate item in the
      collection.

      The provided block will be applied as the template for each item's view.

      Given an empty `<body>` the following template:

      ```handlebars
      {{#collection contentBinding="App.items"}}
        Hi {{view.content.name}}
      {{/collection}}
      ```

      And the following application code

      ```javascript
      App = Ember.Application.create()
      App.items = [
        Ember.Object.create({name: 'Dave'}),
        Ember.Object.create({name: 'Mary'}),
        Ember.Object.create({name: 'Sara'})
      ]
      ```

      Will result in the HTML structure below

      ```html
      <div class="ember-view">
        <div class="ember-view">Hi Dave</div>
        <div class="ember-view">Hi Mary</div>
        <div class="ember-view">Hi Sara</div>
      </div>
      ```

      ### Blockless use in a collection

      If you provide an `itemViewClass` option that has its own `template` you can
      omit the block.

      The following template:

      ```handlebars
      {{collection contentBinding="App.items" itemViewClass="App.AnItemView"}}
      ```

      And application code

      ```javascript
      App = Ember.Application.create();
      App.items = [
        Ember.Object.create({name: 'Dave'}),
        Ember.Object.create({name: 'Mary'}),
        Ember.Object.create({name: 'Sara'})
      ];

      App.AnItemView = Ember.View.extend({
        template: Ember.Handlebars.compile("Greetings {{view.content.name}}")
      });
      ```

      Will result in the HTML structure below

      ```html
      <div class="ember-view">
        <div class="ember-view">Greetings Dave</div>
        <div class="ember-view">Greetings Mary</div>
        <div class="ember-view">Greetings Sara</div>
      </div>
      ```

      ### Specifying a CollectionView subclass

      By default the `{{collection}}` helper will create an instance of
      `Ember.CollectionView`. You can supply a `Ember.CollectionView` subclass to
      the helper by passing it as the first argument:

      ```handlebars
      {{#collection App.MyCustomCollectionClass contentBinding="App.items"}}
        Hi {{view.content.name}}
      {{/collection}}
      ```

      ### Forwarded `item.*`-named Options

      As with the `{{view}}`, helper options passed to the `{{collection}}` will be
      set on the resulting `Ember.CollectionView` as properties. Additionally,
      options prefixed with `item` will be applied to the views rendered for each
      item (note the camelcasing):

      ```handlebars
      {{#collection contentBinding="App.items"
                    itemTagName="p"
                    itemClassNames="greeting"}}
        Howdy {{view.content.name}}
      {{/collection}}
      ```

      Will result in the following HTML structure:

      ```html
      <div class="ember-view">
        <p class="ember-view greeting">Howdy Dave</p>
        <p class="ember-view greeting">Howdy Mary</p>
        <p class="ember-view greeting">Howdy Sara</p>
      </div>
      ```

    /**
      The `{{#each}}` helper loops over elements in a collection, rendering its
      block once for each item. It is an extension of the base Handlebars `{{#each}}`
      helper:

      ```javascript
      Developers = [{name: 'Yehuda'},{name: 'Tom'}, {name: 'Paul'}];
      ```

      ```handlebars
      {{#each Developers}}
        {{name}}
      {{/each}}
      ```

      `{{each}}` supports an alternative syntax with element naming:

      ```handlebars
      {{#each person in Developers}}
        {{person.name}}
      {{/each}}
      ```

      When looping over objects that do not have properties, `{{this}}` can be used
      to render the object:

      ```javascript
      DeveloperNames = ['Yehuda', 'Tom', 'Paul']
      ```

      ```handlebars
      {{#each DeveloperNames}}
        {{this}}
      {{/each}}
      ```
      ### {{else}} condition
      `{{#each}}` can have a matching `{{else}}`. The contents of this block will render
      if the collection is empty.

      ```
      {{#each person in Developers}}
        {{person.name}}
      {{else}}
        <p>Sorry, nobody is available for this task.</p>
      {{/each}}
      ```
      ### Specifying a View class for items
      If you provide an `itemViewClass` option that references a view class
      with its own `template` you can omit the block.

      The following template:

      ```handlebars
      {{#view App.MyView }}
        {{each view.items itemViewClass="App.AnItemView"}}
      {{/view}}
      ```

      And application code

      ```javascript
      App = Ember.Application.create({
        MyView: Ember.View.extend({
          items: [
            Ember.Object.create({name: 'Dave'}),
            Ember.Object.create({name: 'Mary'}),
            Ember.Object.create({name: 'Sara'})
          ]
        })
      });

      App.AnItemView = Ember.View.extend({
        template: Ember.Handlebars.compile("Greetings {{name}}")
      });
      ```

      Will result in the HTML structure below

      ```html
      <div class="ember-view">
        <div class="ember-view">Greetings Dave</div>
        <div class="ember-view">Greetings Mary</div>
        <div class="ember-view">Greetings Sara</div>
      </div>
      ```

      If an `itemViewClass` is defined on the helper, and therefore the helper is not
      being used as a block, an `emptyViewClass` can also be provided optionally.
      The `emptyViewClass` will match the behavior of the `{{else}}` condition
      described above. That is, the `emptyViewClass` will render if the collection
      is empty.

      ### Representing each item with a Controller.
      By default the controller lookup within an `{{#each}}` block will be
      the controller of the template where the `{{#each}}` was used. If each
      item needs to be presented by a custom controller you can provide a
      `itemController` option which references a controller by lookup name.
      Each item in the loop will be wrapped in an instance of this controller
      and the item itself will be set to the `model` property of that controller.

      This is useful in cases where properties of model objects need transformation
      or synthesis for display:

      ```javascript
      App.DeveloperController = Ember.ObjectController.extend({
        isAvailableForHire: function() {
          return !this.get('model.isEmployed') && this.get('model.isSeekingWork');
        }.property('isEmployed', 'isSeekingWork')
      })
      ```

      ```handlebars
      {{#each person in developers itemController="developer"}}
        {{person.name}} {{#if person.isAvailableForHire}}Hire me!{{/if}}
      {{/each}}
      ```

      Each itemController will receive a reference to the current controller as
      a `parentController` property.

      ### (Experimental) Grouped Each

      When used in conjunction with the experimental [group helper](https://github.com/emberjs/group-helper),
      you can inform Handlebars to re-render an entire group of items instead of
      re-rendering them one at a time (in the event that they are changed en masse
      or an item is added/removed).

      ```handlebars
      {{#group}}
        {{#each people}}
          {{firstName}} {{lastName}}
        {{/each}}
      {{/group}}
      ```

      This can be faster than the normal way that Handlebars re-renders items
      in some cases.

      If for some reason you have a group with more than one `#each`, you can make
      one of the collections be updated in normal (non-grouped) fashion by setting
      the option `groupedRows=true` (counter-intuitive, I know).

      For example,

      ```handlebars
      {{dealershipName}}

      {{#group}}
        {{#each dealers}}
          {{firstName}} {{lastName}}
        {{/each}}

        {{#each car in cars groupedRows=true}}
          {{car.make}} {{car.model}} {{car.color}}
        {{/each}}
      {{/group}}
      ```
      Any change to `dealershipName` or the `dealers` collection will cause the
      entire group to be re-rendered. However, changes to the `cars` collection
      will be re-rendered individually (as normal).

      Note that `group` behavior is also disabled by specifying an `itemViewClass`.

      The `partial` helper renders another template without
      changing the template context:

      ```handlebars
      {{foo}}
      {{partial "nav"}}
      ```

      The above example template will render a template named
      "_nav", which has the same context as the parent template
      it's rendered into, so if the "_nav" template also referenced
      `{{foo}}`, it would print the same thing as the `{{foo}}`
      in the above example.

      If a "_nav" template isn't found, the `partial` helper will
      fall back to a template named "nav".

      ## Bound template names

      The parameter supplied to `partial` can also be a path
      to a property containing a template name, e.g.:

      ```handlebars
      {{partial someTemplateName}}
      ```

      The above example will look up the value of `someTemplateName`
      on the template context (e.g. a controller) and use that
      value as the name of the template to render. If the resolved
      value is falsy, nothing will be rendered. If `someTemplateName`
      changes, the partial will be re-rendered using the new template
      name.

      ## Setting the partial's context with `with`

      The `partial` helper can be used in conjunction with the `with`
      helper to set a context that will be used by the partial:

      ```handlebars
      {{#with currentUser}}
        {{partial "user_info"}}
      {{/with}}

    /**
      `{{view}}` inserts a new instance of an `Ember.View` into a template passing its
      options to the `Ember.View`'s `create` method and using the supplied block as
      the view's own template.

      An empty `<body>` and the following template:

      ```handlebars
      A span:
      {{#view tagName="span"}}
        hello.
      {{/view}}
      ```

      Will result in HTML structure:

      ```html
      <body>
        <!-- Note: the handlebars template script
             also results in a rendered Ember.View
             which is the outer <div> here -->

        <div class="ember-view">
          A span:
          <span id="ember1" class="ember-view">
            Hello.
          </span>
        </div>
      </body>
      ```

      ### `parentView` setting

      The `parentView` property of the new `Ember.View` instance created through
      `{{view}}` will be set to the `Ember.View` instance of the template where
      `{{view}}` was called.

      ```javascript
      aView = Ember.View.create({
        template: Ember.Handlebars.compile("{{#view}} my parent: {{parentView.elementId}} {{/view}}")
      });

      aView.appendTo('body');
      ```

      Will result in HTML structure:

      ```html
      <div id="ember1" class="ember-view">
        <div id="ember2" class="ember-view">
          my parent: ember1
        </div>
      </div>
      ```

      ### Setting CSS id and class attributes

      The HTML `id` attribute can be set on the `{{view}}`'s resulting element with
      the `id` option. This option will _not_ be passed to `Ember.View.create`.

      ```handlebars
      {{#view tagName="span" id="a-custom-id"}}
        hello.
      {{/view}}
      ```

      Results in the following HTML structure:

      ```html
      <div class="ember-view">
        <span id="a-custom-id" class="ember-view">
          hello.
        </span>
      </div>
      ```

      The HTML `class` attribute can be set on the `{{view}}`'s resulting element
      with the `class` or `classNameBindings` options. The `class` option will
      directly set the CSS `class` attribute and will not be passed to
      `Ember.View.create`. `classNameBindings` will be passed to `create` and use
      `Ember.View`'s class name binding functionality:

      ```handlebars
      {{#view tagName="span" class="a-custom-class"}}
        hello.
      {{/view}}
      ```

      Results in the following HTML structure:

      ```html
      <div class="ember-view">
        <span id="ember2" class="ember-view a-custom-class">
          hello.
        </span>
      </div>
      ```

      ### Supplying a different view class

      `{{view}}` can take an optional first argument before its supplied options to
      specify a path to a custom view class.

      ```handlebars
      {{#view "MyApp.CustomView"}}
        hello.
      {{/view}}
      ```

      The first argument can also be a relative path accessible from the current
      context.

      ```javascript
      MyApp = Ember.Application.create({});
      MyApp.OuterView = Ember.View.extend({
        innerViewClass: Ember.View.extend({
          classNames: ['a-custom-view-class-as-property']
        }),
        template: Ember.Handlebars.compile('{{#view "view.innerViewClass"}} hi {{/view}}')
      });

      MyApp.OuterView.create().appendTo('body');
      ```

      Will result in the following HTML:

      ```html
      <div id="ember1" class="ember-view">
        <div id="ember2" class="ember-view a-custom-view-class-as-property">
          hi
        </div>
      </div>
      ```

      ### Blockless use

      If you supply a custom `Ember.View` subclass that specifies its own template
      or provide a `templateName` option to `{{view}}` it can be used without
      supplying a block. Attempts to use both a `templateName` option and supply a
      block will throw an error.

      ```handlebars
      {{view "MyApp.ViewWithATemplateDefined"}}
      ```

      ### `viewName` property

      You can supply a `viewName` option to `{{view}}`. The `Ember.View` instance
      will be referenced as a property of its parent view by this name.

      ```javascript
      aView = Ember.View.create({
        template: Ember.Handlebars.compile('{{#view viewName="aChildByName"}} hi {{/view}}')
      });

      aView.appendTo('body');
      aView.get('aChildByName') // the instance of Ember.View created by {{view}} helper
      ```

      @method view
      @for Ember.Handlebars.helpers
      @param {String} path
      @param {Hash} options
      @return {String} HTML string
    */
    function viewHelper(path, options) {
      Ember.assert("The view helper only takes a single argument", arguments.length <= 2);

      // If no path is provided, treat path param as options
      // and get an instance of the registered `view:toplevel`
      if (path && path.data && path.data.isRenderData) {
        options = path;
        Ember.assert('{{view}} helper requires parent view to have a container but none was found. This usually happens when you are manually-managing views.', !!options.data.view.container);
        path = options.data.view.container.lookupFactory('view:toplevel');
      }

      options.helperName = options.helperName || 'view';

      return ViewHelper.helper(this, path, options);
    }

    __exports__.viewHelper = viewHelper;
  });
define("ember-handlebars/helpers/yield",

    /**
      `{{yield}}` denotes an area of a template that will be rendered inside
      of another template. It has two main uses:

      ### Use with `layout`
      When used in a Handlebars template that is assigned to an `Ember.View`
      instance's `layout` property Ember will render the layout template first,
      inserting the view's own rendered output at the `{{yield}}` location.

      An empty `<body>` and the following application code:

      ```javascript
      AView = Ember.View.extend({
        classNames: ['a-view-with-layout'],
        layout: Ember.Handlebars.compile('<div class="wrapper">{{yield}}</div>'),
        template: Ember.Handlebars.compile('<span>I am wrapped</span>')
      });

      aView = AView.create();
      aView.appendTo('body');
      ```

      Will result in the following HTML output:

      ```html
      <body>
        <div class='ember-view a-view-with-layout'>
          <div class="wrapper">
            <span>I am wrapped</span>
          </div>
        </div>
      </body>
      ```

      The `yield` helper cannot be used outside of a template assigned to an
      `Ember.View`'s `layout` property and will throw an error if attempted.

      ```javascript
      BView = Ember.View.extend({
        classNames: ['a-view-with-layout'],
        template: Ember.Handlebars.compile('{{yield}}')
      });

      bView = BView.create();
      bView.appendTo('body');

      // throws
      // Uncaught Error: assertion failed:
      // You called yield in a template that was not a layout
      ```

      ### Use with Ember.Component
      When designing components `{{yield}}` is used to denote where, inside the component's
      template, an optional block passed to the component should render:

      ```handlebars
      <!-- application.hbs -->
      {{#labeled-textfield value=someProperty}}
        First name:
      {{/labeled-textfield}}
      ```

      ```handlebars
      <!-- components/labeled-textfield.hbs -->
      <label>
        {{yield}} {{input value=value}}
      </label>
      ```

      Result:

      ```html
      <label>
        First name: <input type="text" />
      </label>
      ```

      @method yield
      @for Ember.Handlebars.helpers
      @param {Hash} options
      @return {String} HTML string
    */
    __exports__["default"] = function yieldHelper(options) {
      var view = options.data.view;

      while (view && !get(view, 'layout')) {
        if (view._contextView) {
          view = view._contextView;
        } else {
          view = get(view, '_parentView');
        }
      }

    /**
      An `Ember.Binding` connects the properties of two objects so that whenever

      ## Automatic Creation of Bindings with `/^*Binding/`-named Properties

      You do not usually create Binding objects directly but instead describe
      bindings in your class or object definition using automatic binding
      detection.

      Properties ending in a `Binding` suffix will be converted to `Ember.Binding`
      instances. The value of this property should be a string representing a path
      to another object or a custom binding instance created using Binding helpers
      (see "One Way Bindings"):

      ```
      valueBinding: "MyApp.someController.title"
      ```

      This will create a binding from `MyApp.someController.title` to the `value`
      property of your object instance automatically. Now the two values will be
      kept in sync.

      ## One Way Bindings

      One especially useful binding customization you can use is the `oneWay()`
      helper. This helper tells Ember that you are only interested in
      receiving changes on the object you are binding from. For example, if you
      are binding to a preference and you want to be notified if the preference
      has changed, but your object will not be changing the preference itself, you
      could do:

      ```
      bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles")
      ```

      This way if the value of `MyApp.preferencesController.bigTitles` changes the
      `bigTitles` property of your object will change also. However, if you
      change the value of your `bigTitles` property, it will not update the
      `preferencesController`.

      One way bindings are almost twice as fast to setup and twice as fast to
      execute because the binding only has to worry about changes to one side.

      You should consider using one way bindings anytime you have an object that
      may be created frequently and you do not intend to change a property; only
      to monitor it for changes (such as in the example above).

      ## Adding Bindings Manually

      All of the examples above show you how to configure a custom binding, but the
      result of these customizations will be a binding template, not a fully active
      Binding instance. The binding will actually become active only when you
      instantiate the object the binding belongs to. It is useful however, to
      understand what actually happens when the binding is activated.

      For a binding to function it must have at least a `from` property and a `to`
      property. The `from` property path points to the object/key that you want to
      bind from while the `to` path points to the object/key you want to bind to.

      When you define a custom binding, you are usually describing the property
      you want to bind from (such as `MyApp.someController.value` in the examples
      above). When your object is created, it will automatically assign the value
      you want to bind `to` based on the name of your binding key. In the
      examples above, during init, Ember objects will effectively call
      something like this on your binding:

      ```javascript
      binding = Ember.Binding.from("valueBinding").to("value");
      ```

      This creates a new binding instance based on the template you provide, and
      sets the to path to the `value` property of the new object. Now that the
      binding is fully configured with a `from` and a `to`, it simply needs to be
      connected to become active. This is done through the `connect()` method:

      ```javascript
      binding.connect(this);
      ```

      Note that when you connect a binding you pass the object you want it to be
      connected to. This object will be used as the root for both the from and
      to side of the binding when inspecting relative paths. This allows the
      binding to be automatically inherited by subclassed objects as well.

      This also allows you to bind between objects using the paths you declare in
      `from` and `to`:

      ```javascript
      // Example 1
      binding = Ember.Binding.from("App.someObject.value").to("value");
      binding.connect(this);

      // Example 2
      binding = Ember.Binding.from("parentView.value").to("App.someObject.value");
      binding.connect(this);
      ```

      Now that the binding is connected, it will observe both the from and to side
      and relay changes.

      If you ever needed to do so (you almost never will, but it is useful to
      understand this anyway), you could manually create an active binding by
      using the `Ember.bind()` helper method. (This is the same method used by
      to setup your bindings on objects):

      ```javascript
      Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value");
      ```

      Both of these code fragments have the same effect as doing the most friendly
      form of binding creation like so:

      ```javascript
      MyApp.anotherObject = Ember.Object.create({
        valueBinding: "MyApp.someController.value",

        // OTHER CODE FOR THIS OBJECT...
      });
      ```

      Ember's built in binding creation method makes it easy to automatically
      create bindings for you. You should always use the highest-level APIs
      available, even if you understand how it works underneath.

    // COMPUTED PROPERTY
    //

    /**
      A computed property transforms an objects function into a property.

      By default the function backing the computed property will only be called
      once and the result will be cached. You can specify various properties
      that your computed property is dependent on. This will force the cached
      result to be recomputed if the dependencies are modified.

      In the following example we declare a computed property (by calling
      `.property()` on the fullName function) and setup the properties
      dependencies (depending on firstName and lastName). The fullName function
      will be called once (regardless of how many times it is accessed) as long
      as it's dependencies have not been changed. Once firstName or lastName are updated
      any future calls (or anything bound) to fullName will incorporate the new
      values.

      ```javascript
      var Person = Ember.Object.extend({
        // these will be supplied by `create`
        firstName: null,
        lastName: null,

        fullName: function() {
          var firstName = this.get('firstName');
          var lastName = this.get('lastName');

         return firstName + ' ' + lastName;
        }.property('firstName', 'lastName')
      });

      var tom = Person.create({
        firstName: 'Tom',
        lastName: 'Dale'
      });

      tom.get('fullName') // 'Tom Dale'
      ```

      You can also define what Ember should do when setting a computed property.
      If you try to set a computed property, it will be invoked with the key and
      value you want to set it to. You can also accept the previous value as the
      third parameter.

      ```javascript
      var Person = Ember.Object.extend({
        // these will be supplied by `create`
        firstName: null,
        lastName: null,

        fullName: function(key, value, oldValue) {
          // getter
          if (arguments.length === 1) {
            var firstName = this.get('firstName');
            var lastName = this.get('lastName');

            return firstName + ' ' + lastName;

          // setter
          } else {
            var name = value.split(' ');

            this.set('firstName', name[0]);
            this.set('lastName', name[1]);

            return value;
          }
        }.property('firstName', 'lastName')
      });

      var person = Person.create();

      person.set('fullName', 'Peter Wagenet');
      person.get('firstName'); // 'Peter'
      person.get('lastName');  // 'Wagenet'

      The purpose of the Ember Instrumentation module is
      to provide efficient, general-purpose instrumentation
      for Ember.

      Subscribe to a listener by using `Ember.subscribe`:

      ```javascript
      Ember.subscribe("render", {
        before: function(name, timestamp, payload) {

        },

        after: function(name, timestamp, payload) {

        }
      });
      ```

      If you return a value from the `before` callback, that same
      value will be passed as a fourth parameter to the `after`
      callback.

      Instrument a block of code by using `Ember.instrument`:

      ```javascript
      Ember.instrument("render.handlebars", payload, function() {
        // rendering logic
      }, binding);
      ```

      Event names passed to `Ember.instrument` are namespaced
      by periods, from more general to more specific. Subscribers
      can listen for events by whatever level of granularity they
      are interested in.

      In the above example, the event is `render.handlebars`,
      and the subscriber listened for all events beginning with
      `render`. It would receive callbacks for events named
      `render`, `render.handlebars`, `render.container`, or
      even `render.handlebars.layout`.

      JavaScript (before ES6) does not have a Map implementation. Objects,

      Because Ember has a way to get a unique identifier for every object
      via `Ember.guidFor`, we can implement a performant Map with arbitrary
      keys. Because it is commonly used in low-level bookkeeping, Map is
      implemented as a pure JavaScript object for performance.

      This implementation follows the current iteration of the ES6 proposal for
      maps (http://wiki.ecmascript.org/doku.php?id=harmony:simple_maps_and_sets),
      with two exceptions. First, because we need our implementation to be pleasant
      on older browsers, we do not use the `delete` name (using `remove` instead).
      Second, as we do not have the luxury of in-VM iteration, we implement a
      forEach method for iteration.

      Map is mocked out to look like an Ember object, so you can do
      `Ember.Map.create()` for symmetry with other Ember classes.

      The `Ember.Mixin` class allows you to create mixins, whose properties can be
      added to other classes. For instance,

      ```javascript
      App.Editable = Ember.Mixin.create({
        edit: function() {
          console.log('starting to edit');
          this.set('isEditing', true);

      });

      // Mix mixins into classes by passing them as the first arguments to
      // .extend.
      App.CommentView = Ember.View.extend(App.Editable, {
        template: Ember.Handlebars.compile('{{#if view.isEditing}}...{{else}}...{{/if}}')
      });

      commentView = App.CommentView.create();
      commentView.edit(); // outputs 'starting to edit'
      ```

      Note that Mixins are created with `Ember.Mixin.create`, not
      `Ember.Mixin.extend`.

      Note that mixins extend a constructor's prototype so arrays and object literals
      defined as properties will be shared amongst objects that implement the mixin.
      If you want to define a property in a mixin that is not shared, you can define
      it either as a computed property or have it be created on initialization of the object.

      ```javascript
      //filters array will be shared amongst any object implementing mixin
      App.Filterable = Ember.Mixin.create({
        filters: Ember.A()
      });

      //filters will be a separate  array for every object implementing the mixin
      App.Filterable = Ember.Mixin.create({
        filters: Ember.computed(function(){return Ember.A();})
      });

      //filters will be created as a separate array during the object's initialization

      NOTE: This is a low-level method used by other parts of the API. You almost
      never want to call this method directly. Instead you should use
      `Ember.mixin()` to define new properties.

      Defines a property on an object. This method works much like the ES5
      `Object.defineProperty()` method except that it can also accept computed
      properties and other special descriptors.

      Normally this method takes only three parameters. However if you pass an
      instance of `Ember.Descriptor` as the third param then you can pass an
      optional value as the fourth parameter. This is often more efficient than
      creating new descriptor hashes for each property.

      ## Examples

      // ES5 compatible mode
      Ember.defineProperty(contact, 'firstName', {
        writable: true,
        configurable: false,
        enumerable: true,

      // define a simple property
      Ember.defineProperty(contact, 'lastName', undefined, 'Jolley');

      // define a computed property
      Ember.defineProperty(contact, 'fullName', Ember.computed(function() {
        return this.firstName+' '+this.lastName;
      }).property('firstName', 'lastName'));
      ```

      Provides a useful utility for when integrating with non-Ember libraries
      that provide asynchronous callbacks.

      Ember utilizes a run-loop to batch and coalesce changes. This works by
      marking the start and end of Ember-related Javascript execution.

      When using events such as a View's click handler, Ember wraps the event
      handler in a run-loop, but when integrating with non-Ember libraries this
      can be tedious.

      For example, the following is rather verbose but is the correct way to combine
      third-party events and Ember code.

      ```javascript
      var that = this;
      jQuery(window).on('resize', function(){
        run(function(){
          that.handleResize();
        });
      });
      ```

      To reduce the boilerplate, the following can be used to construct a
      run-loop-wrapped callback handler.

      ```javascript
      jQuery(window).on('resize', run.bind(this, this.handleResize));

      Note that although you can pass optional arguments these will not be
      considered when looking for duplicates. New arguments will replace previous
      calls.

      ```

      Also note that passing an anonymous function to `run.scheduleOnce` will
      not prevent additional calls with an identical anonymous function from
      scheduling the items multiple times, e.g.:

      ```javascript
      function scheduleIt() {
        run.scheduleOnce('actions', myContext, function() { console.log("Closure"); });
      }
      scheduleIt();
      scheduleIt();

      // because the function we pass to it is anonymous and won't match the

    /**
      Schedules an item to run from within a separate run loop, after
      control has been returned to the system. This is equivalent to calling
      `run.later` with a wait time of 1ms.

      ```javascript
      run.next(myContext, function() {
        // code to be executed in the next run loop,
        // which will be scheduled after the current one
      });
      ```

      Multiple operations scheduled with `run.next` will coalesce
      into the same later run loop, along with any other operations
      scheduled by `run.later` that expire right around the same
      time that `run.next` operations will fire.

      Note that there are often alternatives to using `run.next`.
      For instance, if you'd like to schedule an operation to happen
      after all DOM element operations have completed within the current
      run loop, you can make use of the `afterRender` run loop queue (added
      by the `ember-views` package, along with the preceding `render` queue
      where all the DOM element operations happen). Example:

      ```javascript
      App.MyCollectionView = Ember.CollectionView.extend({
        didInsertElement: function() {
          run.scheduleOnce('afterRender', this, 'processChildElements');
        },
        processChildElements: function() {
          // ... do something with collectionView's child view
          // elements after they've finished rendering, which
          // can't be done within the CollectionView's
          // `didInsertElement` hook because that gets run
          // before the child elements have been added to the DOM.
        }
      });
      ```

      One benefit of the above approach compared to using `run.next` is
      that you will be able to perform DOM/CSS operations before unprocessed
      elements are rendered to the screen, which may prevent flickering or
      other artifacts caused by delaying processing until after rendering.

      The other major benefit to the above approach is that `run.next`
      introduces an element of non-determinism, which can make things much
      harder to test, due to its reliance on `setTimeout`; it's much harder
      to guarantee the order of scheduled operations when they are scheduled
      outside of the current run loop, i.e. with `run.next`.

      This method should be used when an event may be called multiple times
      but the action should only be called once when the event is done firing.
      A common example is for scroll events where you only want updates to
      happen once scrolling has ceased.

      ```javascript
        var myFunc = function() { console.log(this.name + ' ran.'); };

      other calls for this function until the wait time has elapsed. If

      the timer is reset and the entire period must pass again before
      the method can be called again.

      @deprecated
      @private

      In order to store defaults for a class, a prototype may need to create
      a default meta object, which will be inherited by any objects instantiated
      from the class's constructor.

      However, the properties of that meta object are only shallow-cloned,
      so if a property is a hash (like the event system's `listeners` hash),
      it will by default be shared across all instances of that class.

      This method allows extensions to deeply clone a series of nested hashes or
      other complex objects. For instance, the event system might pass
      `['listeners', 'foo:change', 'ember157']` to `prepareMetaPath`, which will
      walk down the keys provided.

      For each key, if the key does not exist, it is created. If it already
      exists and it was inherited from its constructor, the constructor's
      key is cloned.

      You can also pass false for `writable`, which will simply return
      undefined if `prepareMetaPath` discovers any part of the path that
      shared or undefined.

    /**
      The `{{action}}` helper registers an HTML element within a template for DOM
      event handling and forwards that interaction to the templates's controller
      or supplied `target` option (see 'Specifying a Target').

      If the controller does not implement the event, the event is sent
      to the current route, and it bubbles up the route hierarchy from there.

      User interaction with that element will invoke the supplied action name on
      the appropriate target. Specifying a non-quoted action name will result in
      a bound property lookup at the time the event will be triggered.

      Given the following application Handlebars template on the page

      ```handlebars
      <div {{action 'anActionName'}}>
        click me
      </div>
      ```

      And application code

      ```javascript
      App.ApplicationController = Ember.Controller.extend({
        actions: {
          anActionName: function() {
          }
        }
      });
      ```

      Will result in the following rendered HTML

      ```html
      <div class="ember-view">
        <div data-ember-action="1">
          click me
        </div>
      </div>
      ```

      Clicking "click me" will trigger the `anActionName` action of the
      `App.ApplicationController`. In this case, no additional parameters will be passed.

      If you provide additional parameters to the helper:

      ```handlebars
      <button {{action 'edit' post}}>Edit</button>
      ```

      Those parameters will be passed along as arguments to the JavaScript
      function implementing the action.

      ### Event Propagation

      Events triggered through the action helper will automatically have
      `.preventDefault()` called on them. You do not need to do so in your event
      handlers. If you need to allow event propagation (to handle file inputs for
      example) you can supply the `preventDefault=false` option to the `{{action}}` helper:

      ```handlebars
      <div {{action "sayHello" preventDefault=false}}>
        <input type="file" />
        <input type="checkbox" />
      </div>
      ```

      To disable bubbling, pass `bubbles=false` to the helper:

      ```handlebars
      <button {{action 'edit' post bubbles=false}}>Edit</button>
      ```

      If you need the default handler to trigger you should either register your
      own event handler, or use event methods on your view class. See [Ember.View](/api/classes/Ember.View.html)
      'Responding to Browser Events' for more information.

      ### Specifying DOM event type

      By default the `{{action}}` helper registers for DOM `click` events. You can
      supply an `on` option to the helper to specify a different DOM event name:

      ```handlebars
      <div {{action "anActionName" on="doubleClick"}}>
        click me
      </div>
      ```

      See `Ember.View` 'Responding to Browser Events' for a list of
      acceptable DOM event names.

      NOTE: Because `{{action}}` depends on Ember's event dispatch system it will
      only function if an `Ember.EventDispatcher` instance is available. An
      `Ember.EventDispatcher` instance will be created when a new `Ember.Application`
      is created. Having an instance of `Ember.Application` will satisfy this
      requirement.

      ### Specifying whitelisted modifier keys

      By default the `{{action}}` helper will ignore click event with pressed modifier
      keys. You can supply an `allowedKeys` option to specify which keys should not be ignored.

      ```handlebars
      <div {{action "anActionName" allowedKeys="alt"}}>
        click me
      </div>
      ```

      This way the `{{action}}` will fire when clicking with the alt key pressed down.

      Alternatively, supply "any" to the `allowedKeys` option to accept any combination of modifier keys.

      ```handlebars
      <div {{action "anActionName" allowedKeys="any"}}>
        click me with any key pressed
      </div>
      ```

      ### Specifying a Target

      There are several possible target objects for `{{action}}` helpers:

      In a typical Ember application, where views are managed through use of the
      `{{outlet}}` helper, actions will bubble to the current controller, then
      to the current route, and then up the route hierarchy.

      Alternatively, a `target` option can be provided to the helper to change
      which object will receive the method call. This option must be a path
      to an object, accessible in the current context:

      ```handlebars
      {{! the application template }}
      <div {{action "anActionName" target=view}}>
        click me
      </div>
      ```

      ```javascript
      App.ApplicationView = Ember.View.extend({
        actions: {
          anActionName: function(){}
        }
      });

      ```

      ### Additional Parameters

      You may specify additional parameters to the `{{action}}` helper. These
      parameters are passed along as the arguments to the JavaScript function
      implementing the action.

      ```handlebars
      {{#each person in people}}
        <div {{action "edit" person}}>
          click me
        </div>
      {{/each}}
      ```

      Clicking "click me" will trigger the `edit` method on the current controller
      with the value of `person` as a parameter.

      @method action
      @for Ember.Handlebars.helpers
      @param {String} actionName
      @param {Object} [context]*
      @param {Hash} options

      var action = {
        eventName: hash.on || "click",
        parameters: {
          context: this,

      };

      if (hash.target) {

        action.target.target = hash.target;
      } else if (controller) {

      The `{{link-to}}` helper renders a link to the supplied

      route as its `model` context of the route. The block
      for `{{link-to}}` becomes the innerHTML of the rendered
      element:

      ```handlebars
      {{#link-to 'photoGallery'}}
        Great Hamster Photos
      {{/link-to}}
      ```

      ```html
      <a href="/hamster-photos">
        Great Hamster Photos
      </a>
      ```

      ### Supplying a tagName
      By default `{{link-to}}` renders an `<a>` element. This can
      be overridden for a single use of `{{link-to}}` by supplying
      a `tagName` option:

      ```handlebars
      {{#link-to 'photoGallery' tagName="li"}}
        Great Hamster Photos
      {{/link-to}}
      ```

      ```html
      <li>
        Great Hamster Photos
      </li>
      ```

      To override this option for your entire application, see
      "Overriding Application-wide Defaults".

      ### Disabling the `link-to` helper
      By default `{{link-to}}` is enabled.
      any passed value to `disabled` helper property will disable the `link-to` helper.

      static use: the `disabled` option:

      ```handlebars
      {{#link-to 'photoGallery' disabled=true}}
        Great Hamster Photos
      {{/link-to}}
      ```

      dynamic use: the `disabledWhen` option:

      ```handlebars
      {{#link-to 'photoGallery' disabledWhen=controller.someProperty}}
        Great Hamster Photos
      {{/link-to}}
      ```

      any passed value to `disabled` will disable it except `undefined`.
      to ensure that only `true` disable the `link-to` helper you can
      override the global behaviour of `Ember.LinkView`.

      ```javascript
      Ember.LinkView.reopen({
        disabled: Ember.computed(function(key, value) {
          if (value !== undefined) {
            this.set('_isDisabled', value === true);
          }
          return value === true ? get(this, 'disabledClass') : false;
        })
      });
      ```

      see "Overriding Application-wide Defaults" for more.

      ### Handling `href`
      `{{link-to}}` will use your application's Router to
      fill the element's `href` property with a url that
      matches the path to the supplied `routeName` for your
      routers's configured `Location` scheme, which defaults
      to Ember.HashLocation.

      ### Handling current route
      `{{link-to}}` will apply a CSS class name of 'active'
      when the application's current route matches
      the supplied routeName. For example, if the application's
      current route is 'photoGallery.recent' the following
      use of `{{link-to}}`:

      ```handlebars
      {{#link-to 'photoGallery.recent'}}
        Great Hamster Photos from the last week
      {{/link-to}}
      ```

      will result in

      ```html
      <a href="/hamster-photos/this-week" class="active">
        Great Hamster Photos
      </a>
      ```

      The CSS class name used for active classes can be customized
      for a single use of `{{link-to}}` by passing an `activeClass`
      option:

      ```handlebars
      {{#link-to 'photoGallery.recent' activeClass="current-url"}}
        Great Hamster Photos from the last week
      {{/link-to}}
      ```

      ```html
      <a href="/hamster-photos/this-week" class="current-url">
        Great Hamster Photos
      </a>
      ```

      To override this option for your entire application, see
      "Overriding Application-wide Defaults".

      ### Supplying a model
      An optional model argument can be used for routes whose
      paths contain dynamic segments. This argument will become
      the model context of the linked route:

      ```javascript
      App.Router.map(function() {
        this.resource("photoGallery", {path: "hamster-photos/:photo_id"});
      });
      ```

      ```handlebars
      {{#link-to 'photoGallery' aPhoto}}
        {{aPhoto.title}}
      {{/link-to}}
      ```

      ```html
      <a href="/hamster-photos/42">
        Tomster
      </a>
      ```

      ### Supplying multiple models
      For deep-linking to route paths that contain multiple
      dynamic segments, multiple model arguments can be used.
      As the router transitions through the route path, each
      supplied model argument will become the context for the
      route with the dynamic segments:

      ```javascript
      App.Router.map(function() {
        this.resource("photoGallery", {path: "hamster-photos/:photo_id"}, function() {
          this.route("comment", {path: "comments/:comment_id"});
        });
      });
      ```
      This argument will become the model context of the linked route:

      ```handlebars
      {{#link-to 'photoGallery.comment' aPhoto comment}}
        {{comment.body}}
      {{/link-to}}
      ```

      ```html
      <a href="/hamster-photos/42/comment/718">
        A+++ would snuggle again.
      </a>
      ```

      ### Supplying an explicit dynamic segment value
      If you don't have a model object available to pass to `{{link-to}}`,
      an optional string or integer argument can be passed for routes whose
      paths contain dynamic segments. This argument will become the value
      of the dynamic segment:

      ```javascript
      App.Router.map(function() {
        this.resource("photoGallery", {path: "hamster-photos/:photo_id"});
      });
      ```

      ```handlebars
      {{#link-to 'photoGallery' aPhotoId}}
        {{aPhoto.title}}
      {{/link-to}}
      ```

      ```html
      <a href="/hamster-photos/42">
        Tomster
      </a>
      ```

      When transitioning into the linked route, the `model` hook will
      be triggered with parameters including this passed identifier.

      ### Allowing Default Action

     By default the `{{link-to}}` helper prevents the default browser action
     by calling `preventDefault()` as this sort of action bubbling is normally
     handled internally and we do not want to take the browser to a new URL (for
     example).

     If you need to override this behavior specify `preventDefault=false` in
     your template:

      ```handlebars
      {{#link-to 'photoGallery' aPhotoId preventDefault=false}}
        {{aPhotoId.title}}
      {{/link-to}}
      ```

      ### Overriding attributes
      You can override any given property of the Ember.LinkView
      that is generated by the `{{link-to}}` helper by passing
      key/value pairs, like so:

      ```handlebars
      {{#link-to  aPhoto tagName='li' title='Following this link will change your life' classNames='pic sweet'}}
        Uh-mazing!
      {{/link-to}}
      ```

      See [Ember.LinkView](/api/classes/Ember.LinkView.html) for a
      complete list of overrideable properties. Be sure to also
      check out inherited properties of `LinkView`.

      ### Overriding Application-wide Defaults
      ``{{link-to}}`` creates an instance of Ember.LinkView
      for rendering. To override options for your entire
      application, reopen Ember.LinkView and supply the
      desired values:

      ``` javascript
      Ember.LinkView.reopen({
        activeClass: "is-active",
        tagName: 'li'
      })
      ```

      It is also possible to override the default event in
      this manner:

      ``` javascript
      Ember.LinkView.reopen({
        eventName: 'customEventName'
      });
      ```

      @method link-to
      @for Ember.Handlebars.helpers
      @param {String} routeName
      @param {Object} [context]*
      @param [options] {Object} Handlebars key/value pairs of options, you can override any property of Ember.LinkView

      The `outlet` helper is a placeholder that the router will fill in with
      the appropriate template based on the current state of the application.

      ``` handlebars
      {{outlet}}
      ```

      By default, a template based on Ember's naming conventions will be rendered
      into the `outlet` (e.g. `App.PostsRoute` will render the `posts` template).

      You can render a different template by using the `render()` method in the
      route's `renderTemplate` hook. The following will render the `favoritePost`
      template into the `outlet`.

      ``` javascript
      App.PostsRoute = Ember.Route.extend({
        renderTemplate: function() {
          this.render('favoritePost');
        }
      });
      ```

      You can create custom named outlets for more control.

      ``` handlebars
      {{outlet 'favoritePost'}}
      {{outlet 'posts'}}
      ```

      Then you can define what template is rendered into each outlet in your
      route.


      ``` javascript
      App.PostsRoute = Ember.Route.extend({
        renderTemplate: function() {
          this.render('favoritePost', { outlet: 'favoritePost' });
          this.render('posts', { outlet: 'posts' });
        }
      });
      ```

      You can specify the view that the outlet uses to contain and manage the
      templates rendered into it.

      ``` handlebars
      {{outlet view='sectionContainer'}}
      ```

      ``` javascript
      App.SectionContainer = Ember.ContainerView.extend({
        tagName: 'section',
        classNames: ['special']
      });
      ```

      @method outlet
      @for Ember.Handlebars.helpers
      @param {String} property the property on the controller
        that holds the view for this outlet
      @return {String} HTML string

    /**
      Calling ``{{render}}`` from within a template will insert another
      template that matches the provided name. The inserted template will
      access its properties on its own controller (rather than the controller
      of the parent template).

      If a view class with the same name exists, the view class also will be used.

      Note: A given controller may only be used *once* in your app in this manner.
      A singleton instance of the controller will be created for you.

      Example:

      ```javascript
      App.NavigationController = Ember.Controller.extend({
        who: "world"
      });
      ```

      ```handlebars
      <!-- navigation.hbs -->
      Hello, {{who}}.
      ```

      ```handelbars
      <!-- application.hbs -->
      <h1>My great app</h1>
      {{render "navigation"}}
      ```

      ```html
      <h1>My great app</h1>
      <div class='ember-view'>
        Hello, world.
      </div>
      ```

      Optionally you may provide a second argument: a property path
      that will be bound to the `model` property of the controller.

      If a `model` property path is specified, then a new instance of the
      controller will be created and `{{render}}` can be used multiple times
      with the same name.

     For example if you had this `author` template.

     ```handlebars
    <div class="author">
    Written by {{firstName}} {{lastName}}.
    Total Posts: {{postCount}}
    </div>
    ```

    You could render it inside the `post` template using the `render` helper.

    ```handlebars
    <div class="post">
    <h1>{{title}}</h1>
    <div>{{body}}</div>
    {{render "author" author}}
    </div>
     ```

      Ember.Location returns an instance of the correct implementation of
      the `location` API.

      ## Implementations

      You can pass an implementation name (`hash`, `history`, `none`) to force a
      particular implementation to be used in your application.

      ### HashLocation

      Using `HashLocation` results in URLs with a `#` (hash sign) separating the
      server side URL portion of the URL from the portion that is used by Ember.
      This relies upon the `hashchange` event existing in the browser.

      Example:

      ```javascript
      App.Router.map(function() {
        this.resource('posts', function() {
          this.route('new');
        });
      });

      App.Router.reopen({
        location: 'hash'
      });
      ```

      This will result in a posts.new url of `/#/posts/new`.

      ### HistoryLocation

      Using `HistoryLocation` results in URLs that are indistinguishable from a
      standard URL. This relies upon the browser's `history` API.

      Example:

      ```javascript
      App.Router.map(function() {
        this.resource('posts', function() {
          this.route('new');
        });
      });

      App.Router.reopen({
        location: 'history'
      });
      ```

      This will result in a posts.new url of `/posts/new`.

      Keep in mind that your server must serve the Ember app at all the routes you
      define.

      ### AutoLocation

      Using `AutoLocation`, the router will use the best Location class supported by
      the browser it is running in.

      Browsers that support the `history` API will use `HistoryLocation`, those that
      do not, but still support the `hashchange` event will use `HashLocation`, and
      in the rare case neither is supported will use `NoneLocation`.

      Example:

      ```javascript
      App.Router.map(function() {
        this.resource('posts', function() {
          this.route('new');
        });
      });

      App.Router.reopen({
        location: 'auto'
      });
      ```

      This will result in a posts.new url of `/posts/new` for modern browsers that
      support the `history` api or `/#/posts/new` for older ones, like Internet
      Explorer 9 and below.

      When a user visits a link to your application, they will be automatically
      upgraded or downgraded to the appropriate `Location` class, with the URL
      transformed accordingly, if needed.

      Keep in mind that since some of your users will use `HistoryLocation`, your
      server must serve the Ember app at all the routes you define.

      ### NoneLocation

      Using `NoneLocation` causes Ember to not store the applications URL state
      in the actual URL. This is generally used for testing purposes, and is one
      of the changes made when calling `App.setupForTesting()`.

      ## Location API

      Each location implementation must provide the following methods:

      * implementation: returns the string name used to reference the implementation.
      * getURL: returns the current URL.
      * setURL(path): sets the current URL.
      * replaceURL(path): replace the current URL (optional).
      * onUpdateURL(callback): triggers the callback when the URL changes.
      * formatURL(url): formats `url` to be placed into `href` attribute.

      Calling setURL or replaceURL will not trigger onUpdateURL callbacks.

        This is useful when multiple routes would benefit from using the same view

        using this property.

        This is useful in many ways, as the controller specified will be:

        * passed to the `setupController` method.
        * used as the controller for the view being rendered by the route.

        argument. This action can be used for aborting, redirecting,
        or decorating the transition from the currently active routes.

        A good example is preventing navigation when a form is
        half-filled out:

        ```js
        App.ContactFormRoute = Ember.Route.extend({
          actions: {
            willTransition: function(transition) {

            }
          }
        });
        ```

        You can also redirect elsewhere by calling
        `this.transitionTo('elsewhere')` from within `willTransition`.
        Note that `willTransition` will not be fired for the
        redirecting `transitionTo`, since `willTransition` doesn't
        fire when there is already a transition underway. If you want
        subsequent `willTransition` actions to fire for the redirecting
        transition, you must first explicitly call
        `transition.abort()`.

        When attempting to transition into a route, any of the hooks

        action will be fired on the partially-entered routes, allowing
        for per-route error handling logic, or shared error handling
        logic defined on a parent route.

        Here is an example of an error handler that will be invoked
        for rejected promises from the various hooks on the route,
        as well as any unhandled errors from child routes:

        ```js
        App.AdminRoute = Ember.Route.extend({
          beforeModel: function() {
            return Ember.RSVP.reject("bad things!");
          },

          actions: {
            error: function(error, transition) {
              // Assuming we got here due to the error in `beforeModel`,
              // we can expect that error === "bad things!",
              // but a promise model rejecting would also
              // call this hook, as would any errors encountered
              // in `afterModel`.

              // The `error` hook is also provided the failed
              // `transition`, which can be stored and later
              // `.retry()`d if desired.

              this.transitionTo('login');
            }
          }
        });
        ```

        `error` actions that bubble up all the way to `ApplicationRoute`
        will fire a default error handler that logs the error. You can
        specify your own global default error handler by overriding the
        `error` handler on `ApplicationRoute`:

        ```js
        App.ApplicationRoute = Ember.Route.extend({
          actions: {
            error: function(error, transition) {
              this.controllerFor('banner').displayError(error.message);
            }
          }
        });
        ```

        this.transitionTo('blogPosts.recentEntries');

        Optionally supply a model for the route in question. The model
        will be serialized into the URL using the `serialize` hook of
        the route:

        ```javascript
        this.transitionTo('blogPost', aPost);
        ```

        If a literal is passed (such as a number or a string), it will
        be treated as an identifier instead. In this case, the `model`
        hook of the route will be triggered:

        ```javascript
        this.transitionTo('blogPost', 1);
        ```

        Multiple models will be applied last to first recursively up the
        resource tree.

        this.transitionTo('blogComment', aPost, aComment);
        this.transitionTo('blogComment', 1, 13);
        ```

        It is also possible to pass a URL (a string that starts with a
        `/`). This is intended for testing and debugging purposes and
        should rarely be used in production code.

        ```javascript
        this.transitionTo('/');
        this.transitionTo('/blog/post/1/comment/13');
        ```

        See also 'replaceWith'.

          this.route("index");
          this.route("secret");

        });
        ```

        Transition to a nested route

      /**
        This hook is the first of the route entry validation hooks
        called when an attempt is made to transition into a route
        or one of its children. It is called before `model` and
        `afterModel`, and is appropriate for cases when:

        1) A decision can be made to redirect elsewhere without
           needing to resolve the model first.
        2) Any async operations need to occur first before the
           model is attempted to be resolved.

        This hook is provided the current `transition` attempt
        as a parameter, which can be used to `.abort()` the transition,
        save it for a later `.retry()`, or retrieve values set
        on it from a previous hook. You can also just call
        `this.transitionTo` to another route to implicitly
        abort the `transition`.

        You can return a promise from this hook to pause the
        transition until the promise resolves (or rejects). This could
        be useful, for instance, for retrieving async code from
        the server that is required to enter a route.

        ```js
        App.PostRoute = Ember.Route.extend({
          beforeModel: function(transition) {
            if (!App.Post) {
              return Ember.$.getScript('/models/post.js');
            }
          }
        });
        ```

        If `App.Post` doesn't exist in the above example,
        `beforeModel` will use jQuery's `getScript`, which
        returns a promise that resolves after the server has
        successfully retrieved and executed the code from the
        server. Note that if an error were to occur, it would
        be passed to the `error` hook on `Ember.Route`, but
        it's also possible to handle errors specific to
        `beforeModel` right from within the hook (to distinguish
        from the shared error handling behavior of the `error`
        hook):

        ```js
        App.PostRoute = Ember.Route.extend({
          beforeModel: function(transition) {
            if (!App.Post) {
              var self = this;
              return Ember.$.getScript('post.js').then(null, function(e) {
                self.transitionTo('help');

                // Note that the above transitionTo will implicitly
                // halt the transition. If you were to return
                // nothing from this promise reject handler,
                // according to promise semantics, that would
                // convert the reject into a resolve and the
                // transition would continue. To propagate the
                // error so that it'd be handled by the `error`
                // hook, you would have to either
                return Ember.RSVP.reject(e);
              });
            }
          }
        });

        to enter this route, and will result in this route's `beforeModel`,
        `model`, and `afterModel` hooks being fired again within
        the new, redirecting transition. Redirects that occur within
        the `redirect` hook, on the other hand, will _not_ cause
        these hooks to be fired again the second time around; in
        other words, by the time the `redirect` hook has been called,
        both the resolved model and attempted entry into this route
        are considered to be fully validated.

        @method redirect
        @param {Object} model the model for this route
        @param {Transition} transition the transition object associated with the current transition

      /**
        Called when the context is changed by router.js.

        A hook you can implement to convert the URL into the model for
        this route.

        ```js
        App.Router.map(function() {
          this.resource('post', {path: '/posts/:post_id'});
        });
        ```

        The model for the `post` route is `App.Post.find(params.post_id)`.

        By default, if your route has a dynamic segment ending in `_id`:

        * The model class is determined from the segment (`post_id`'s
          class is `App.Post`)
        * The find method is called on the model class with the value of
          the dynamic segment.

        Note that for routes with dynamic segments, this hook is not always
        executed. If the route is entered through a transition (e.g. when
        using the `link-to` Handlebars helper or the `transitionTo` method
        of routes), and a model context is already provided this hook
        is not called.

        A model context does not include a primitive string or number,
        which does cause the model hook to be called.

        Routes without dynamic segments will always execute the model hook.

        ```js
        // no dynamic segment, model hook always called
        this.transitionTo('posts');

        // model passed in, so model hook not called
        thePost = store.find('post', 1);
        this.transitionTo('post', thePost);

        // integer passed in, model hook is called
        this.transitionTo('post', 1);
        ```


        This hook follows the asynchronous/promise semantics
        described in the documentation for `beforeModel`. In particular,
        if a promise returned from `model` fails, the error will be
        handled by the `error` hook on `Ember.Route`.

        Example

        ```js
        App.PostRoute = Ember.Route.extend({
          model: function(params) {
            return App.Post.find(params.post_id);
          }
        });
        ```

        @param {Object} queryParams the query params for this route
        @return {Object|Promise} the model for this route. If
          a promise is returned, the transition will pause until
          the promise resolves, and the resolved value of the promise
          will be used as the model for this route.

        A hook you can use to setup the controller for the current route.

        This method is called with the controller for the current route and the
        model supplied by the `model` hook.

        By default, the `setupController` hook sets the `model` property of
        the controller to the `model`.

        If you implement the `setupController` hook in your Route, it will
        prevent this default behavior. If you want to preserve that behavior
        when implementing your `setupController` function, make sure to call
        `_super`:

        ```js
        App.PhotosRoute = Ember.Route.extend({
          model: function() {
            return App.Photo.find();
          },

          setupController: function (controller, model) {
            // Call _super for default behavior
            this._super(controller, model);
            // Implement your custom setup after
            this.controllerFor('application').set('showingPhotos', true);
          }
        });
        ```

        This means that your template will get a proxy for the model as its
        context, and you can act as though the model itself was the context.

        The provided controller will be one resolved based on the name
        of this route.

        If no explicit controller is defined, Ember will automatically create
        an appropriate controller for the model.

        * if the model is an `Ember.Array` (including record arrays from Ember
          Data), the controller is an `Ember.ArrayController`.
        * otherwise, the controller is an `Ember.ObjectController`.

        As an example, consider the router:

        ```js
        App.Router.map(function() {
          this.resource('post', {path: '/posts/:post_id'});
        });
        ```

        For the `post` route, a controller named `App.PostController` would
        be used if it is defined. If it is not defined, an `Ember.ObjectController`
        instance would be used.

        Example

        ```js
        App.PostRoute = Ember.Route.extend({
          setupController: function(controller, model) {
            controller.set('model', model);
          }
        });
        ```

      },

      */

      },

      /**
        `render` is used to render a template into a region of another template
        (indicated by an `{{outlet}}`). `render` is used both during the entry
        phase of routing (via the `renderTemplate` hook) and later in response to
        user interaction.

        For example, given the following minimal router and templates:

        ```js
        Router.map(function() {
          this.resource('photos');
        });
        ```

        ```handlebars
        <!-- application.hbs -->
        <div class='something-in-the-app-hbs'>
          {{outlet "anOutletName"}}
        </div>
        ```

        ```handlebars
        <!-- photos.hbs -->
        <h1>Photos</h1>
        ```

        You can render `photos.hbs` into the `"anOutletName"` outlet of
        `application.hbs` by calling `render`:

        ```js
        // posts route
        Ember.Route.extend({
          renderTemplate: function(){
            this.render('posts', {
              into: 'application',
              outlet: 'anOutletName'
            })
          }
        });
        ```

        `render` additionally allows you to supply which `view`, `controller`, and
        `model` objects should be loaded and associated with the rendered template.


        ```js
        // posts route
        Ember.Route.extend({
          renderTemplate: function(controller, model){
            this.render('posts', {    // the template to render, referenced by name
              into: 'application',    // the template to render into, referenced by name
              outlet: 'anOutletName', // the outlet inside `options.template` to render into.
              view: 'aViewName',      // the view to use for this template, referenced by name
              controller: 'someControllerName', // the controller to use for this template, referenced by name
              model: model            // the model to set on `options.controller`.
            })
          }
        });
        ```

        The string values provided for the template name, view, and controller
        will eventually pass through to the resolver for lookup. See
        Ember.Resolver for how these are mapped to JavaScript objects in your
        application.

        Not all options need to be passed to `render`. Default values will be used
        based on the name of the route specified in the router or the Route's
        `controllerName`, `viewName` and and `templateName` properties.

        For example:

        ```js
        // router
        Router.map(function() {
          this.route('index');
          this.resource('post', {path: '/posts/:post_id'});
        });
        ```

        ```js
        // post route
        PostRoute = App.Route.extend({
          renderTemplate: function() {
            this.render(); // all defaults apply
          }
        });
        ```

        The name of the `PostRoute`, defined by the router, is `post`.

        The following equivalent default options will be applied when
        the Route calls `render`:

        ```js
        //
        this.render('post', {  // the template name associated with 'post' Route
          into: 'application', // the parent route to 'post' Route
          outlet: 'main',      // {{outlet}} and {{outlet 'main' are synonymous}},
          view: 'post',        // the view associated with the 'post' Route
          controller: 'post',  // the controller associated with the 'post' Route
        })
        ```

        By default the controller's `model` will be the route's model, so it does not
        need to be passed unless you wish to change which model is being used.

        @method render
        @param {String} name the name of the template to render
        @param {Object} [options] the options
        @param {String} [options.into] the template to render into,

        Disconnects a view that has been rendered into an outlet.

        You may pass any or all of the following options to `disconnectOutlet`:

        * `outlet`: the name of the outlet to clear (default: 'main')
        * `parentView`: the name of the view containing the outlet to clear
           (default: the view rendered by the parent route)

        Example:

        ```js
        App.ApplicationRoute = App.Route.extend({
          actions: {
            showModal: function(evt) {

    /**
      Creates a computed property which operates on dependent arrays and
      is updated with "one at a time" semantics. When items are added or
      removed from the dependent array(s) an array computed only operates
      on the change instead of re-evaluating the entire array. This should
      return an array, if you'd like to use "one at a time" semantics and
      compute some value other then an array look at
      `Ember.reduceComputed`.

      If there are more than one arguments the first arguments are
      considered to be dependent property keys. The last argument is
      required to be an options object. The options object can have the
      following three properties.

      `initialize` - An optional initialize function. Typically this will be used
      to set up state on the instanceMeta object.

      `removedItem` - A function that is called each time an element is
      removed from the array.

      `addedItem` - A function that is called each time an element is
      added to the array.


      The `initialize` function has the following signature:

      ```javascript
      function(array, changeMeta, instanceMeta)
      ```

      `array` - The initial value of the arrayComputed, an empty array.

      `changeMeta` - An object which contains meta information about the
      computed. It contains the following properties:

         - `property` the computed property
         - `propertyName` the name of the property on the object

      `instanceMeta` - An object that can be used to store meta
      information needed for calculating your computed. For example a
      unique computed might use this to store the number of times a given
      element is found in the dependent array.


      The `removedItem` and `addedItem` functions both have the following signature:

      ```javascript
      function(accumulatedValue, item, changeMeta, instanceMeta)
      ```

      `accumulatedValue` - The value returned from the last time
      `removedItem` or `addedItem` was called or an empty array.

      `item` - the element added or removed from the array

      `changeMeta` - An object which contains meta information about the
      change. It contains the following properties:

        - `property` the computed property
        - `propertyName` the name of the property on the object
        - `index` the index of the added or removed item
        - `item` the added or removed item: this is exactly the same as
          the second arg
        - `arrayChanged` the array that triggered the change. Can be
          useful when depending on multiple arrays.

      For property changes triggered on an item property change (when
      depKey is something like `someArray.@each.someProperty`),
      `changeMeta` will also contain the following property:

        - `previousValues` an object whose keys are the properties that changed on
        the item, and whose values are the item's previous values.

      `previousValues` is important Ember coalesces item property changes via
      Ember.run.once. This means that by the time removedItem gets called, item has
      the new values, but you may need the previous value (eg for sorting &
      filtering).

      `instanceMeta` - An object that can be used to store meta
      information needed for calculating your computed. For example a
      unique computed might use this to store the number of times a given
      element is found in the dependent array.

      The `removedItem` and `addedItem` functions should return the accumulated
      value. It is acceptable to not return anything (ie return undefined)
      to invalidate the computation. This is generally not a good idea for
      arrayComputed but it's used in eg max and min.

      Example

      ```javascript
      Ember.computed.map = function(dependentKey, callback) {
        var options = {
          addedItem: function(array, item, changeMeta, instanceMeta) {
            var mapped = callback(item);
            array.insertAt(changeMeta.index, mapped);
            return array;
          },
          removedItem: function(array, item, changeMeta, instanceMeta) {
            array.removeAt(changeMeta.index, 1);
            return array;
          }
        };

        return Ember.arrayComputed(dependentKey, options);
      };
      ```

    /**
      Creates a computed property which operates on dependent arrays and
      is updated with "one at a time" semantics. When items are added or
      removed from the dependent array(s) a reduce computed only operates
      on the change instead of re-evaluating the entire array.

      If there are more than one arguments the first arguments are
      considered to be dependent property keys. The last argument is
      required to be an options object. The options object can have the
      following four properties:

      `initialValue` - A value or function that will be used as the initial
      value for the computed. If this property is a function the result of calling
      the function will be used as the initial value. This property is required.

      `initialize` - An optional initialize function. Typically this will be used
      to set up state on the instanceMeta object.

      `removedItem` - A function that is called each time an element is removed
      from the array.

      `addedItem` - A function that is called each time an element is added to
      the array.


      The `initialize` function has the following signature:

      ```javascript
      function(initialValue, changeMeta, instanceMeta)
      ```

      `initialValue` - The value of the `initialValue` property from the
      options object.

      `changeMeta` - An object which contains meta information about the
      computed. It contains the following properties:

         - `property` the computed property
         - `propertyName` the name of the property on the object

      `instanceMeta` - An object that can be used to store meta
      information needed for calculating your computed. For example a
      unique computed might use this to store the number of times a given
      element is found in the dependent array.


      The `removedItem` and `addedItem` functions both have the following signature:

      ```javascript
      function(accumulatedValue, item, changeMeta, instanceMeta)
      ```

      `accumulatedValue` - The value returned from the last time
      `removedItem` or `addedItem` was called or `initialValue`.

      `item` - the element added or removed from the array

      `changeMeta` - An object which contains meta information about the
      change. It contains the following properties:

        - `property` the computed property
        - `propertyName` the name of the property on the object
        - `index` the index of the added or removed item
        - `item` the added or removed item: this is exactly the same as
          the second arg
        - `arrayChanged` the array that triggered the change. Can be
          useful when depending on multiple arrays.

      For property changes triggered on an item property change (when
      depKey is something like `someArray.@each.someProperty`),
      `changeMeta` will also contain the following property:

        - `previousValues` an object whose keys are the properties that changed on
        the item, and whose values are the item's previous values.

      `previousValues` is important Ember coalesces item property changes via
      Ember.run.once. This means that by the time removedItem gets called, item has
      the new values, but you may need the previous value (eg for sorting &
      filtering).

      `instanceMeta` - An object that can be used to store meta
      information needed for calculating your computed. For example a
      unique computed might use this to store the number of times a given
      element is found in the dependent array.

      The `removedItem` and `addedItem` functions should return the accumulated
      value. It is acceptable to not return anything (ie return undefined)
      to invalidate the computation. This is generally not a good idea for
      arrayComputed but it's used in eg max and min.

      Note that observers will be fired if either of these functions return a value
      that differs from the accumulated value.  When returning an object that
      mutates in response to array changes, for example an array that maps
      everything from some other array (see `Ember.computed.map`), it is usually
      important that the *same* array be returned to avoid accidentally triggering observers.

      Example

      ```javascript
      Ember.computed.max = function(dependentKey) {
        return Ember.reduceComputed(dependentKey, {
          initialValue: -Infinity,

          addedItem: function(accumulatedValue, item, changeMeta, instanceMeta) {
            return Math.max(accumulatedValue, item);
          },

          removedItem: function(accumulatedValue, item, changeMeta, instanceMeta) {
            if (item < accumulatedValue) {
              return accumulatedValue;
            }
          }
        });
      };
      ```

      Dependent keys may refer to `@this` to observe changes to the object itself,
      which must be array-like, rather than a property of the object.  This is
      mostly useful for array proxies, to ensure objects are retrieved via
      `objectAtContent`.  This is how you could sort items by properties defined on an item controller.

      Example

      ```javascript
      App.PeopleController = Ember.ArrayController.extend({
        itemController: 'person',

        sortedPeople: Ember.computed.sort('@this.@each.reversedName', function(personA, personB) {
          // `reversedName` isn't defined on Person, but we have access to it via
          // the item controller App.PersonController.  If we'd used
          // `content.@each.reversedName` above, we would be getting the objects
          // directly and not have access to `reversedName`.
          //
          var reversedNameA = get(personA, 'reversedName'),
              reversedNameB = get(personB, 'reversedName');

          return Ember.compare(reversedNameA, reversedNameB);
        })
      });

      App.PersonController = Ember.ObjectController.extend({
        reversedName: function() {
          return reverse(get(this, 'name'));
        }.property('name')
      });
      ```

      Dependent keys whose values are not arrays are treated as regular
      dependencies: when they change, the computed property is completely
      recalculated.  It is sometimes useful to have dependent arrays with similar
      semantics.  Dependent keys which end in `.[]` do not use "one at a time"
      semantics.  When an item is added or removed from such a dependency, the
      computed property is completely recomputed.

      When the computed property is completely recomputed, the `accumulatedValue`
      is discarded, it starts with `initialValue` again, and each item is passed
      to `addedItem` in turn.

      Example

      ```javascript
      Ember.Object.extend({
        // When `string` is changed, `computed` is completely recomputed.
        string: 'a string',

        // When an item is added to `array`, `addedItem` is called.
        array: [],

        // When an item is added to `anotherArray`, `computed` is completely
        // recomputed.
        anotherArray: [],

        computed: Ember.reduceComputed('string', 'array', 'anotherArray.[]', {
          addedItem: addedItemCallback,
          removedItem: removedItemCallback
        })
      });
      ```

      A computed property which returns a new array with all the
      properties from the first dependent array sorted based on a property
      or sort function.

      The callback method you provide should have the following signature:

      ```javascript
      function(itemA, itemB);
      ```

      - `itemA` the first item to compare.
      - `itemB` the second item to compare.

      This function should return negative number (e.g. `-1`) when `itemA` should come before
      `itemB`. It should return positive number (e.g. `1`) when `itemA` should come after
      `itemB`. If the `itemA` and `itemB` are equal this function should return `0`.

      Therefore, if this function is comparing some numeric values, simple `itemA - itemB` or
      `itemA.get( 'foo' ) - itemB.get( 'foo' )` can be used instead of series of `if`.

    /**
      `Ember.ArrayController` provides a way for you to publish a collection of
      objects so that you can easily bind to the collection from a Handlebars
      `#each` helper, an `Ember.CollectionView`, or other controllers.

      The advantage of using an `ArrayController` is that you only have to set up
      your view bindings once; to change what's displayed, simply swap out the
      `model` property on the controller.

      For example, imagine you wanted to display a list of items fetched via an XHR
      request. Create an `Ember.ArrayController` and set its `model` property:

      ```javascript
      MyApp.listController = Ember.ArrayController.create();

      $.get('people.json', function(data) {
        MyApp.listController.set('model', data);
      });
      ```

      Then, create a view that binds to your new controller:

      ```handlebars
      {{#each MyApp.listController}}
        {{firstName}} {{lastName}}
      {{/each}}
      ```

      Although you are binding to the controller, the behavior of this controller
      is to pass through any methods or properties to the underlying array. This
      capability comes from `Ember.ArrayProxy`, which this class inherits from.

      Sometimes you want to display computed properties within the body of an
      `#each` helper that depend on the underlying items in `model`, but are not
      present on those items.   To do this, set `itemController` to the name of a
      controller (probably an `ObjectController`) that will wrap each individual item.

      For example:

      ```handlebars
        {{#each post in controller}}
          <li>{{post.title}} ({{post.titleLength}} characters)</li>
        {{/each}}
      ```

      ```javascript
      App.PostsController = Ember.ArrayController.extend({
        itemController: 'post'
      });

      App.PostController = Ember.ObjectController.extend({
        // the `title` property will be proxied to the underlying post.

        titleLength: function() {
          return this.get('title').length;
        }.property('title')
      });
      ```

      In some cases it is helpful to return a different `itemController` depending
      on the particular item.  Subclasses can do this by overriding
      `lookupItemController`.

      For example:

      ```javascript
      App.MyArrayController = Ember.ArrayController.extend({
        lookupItemController: function( object ) {
          if (object.get('isSpecial')) {
            return "special"; // use App.SpecialController
          } else {
            return "regular"; // use App.RegularController
          }
        }
      });
      ```

      The itemController instances will have a `parentController` property set to
      the `ArrayController` instance.

      @extends Ember.ArrayProxy

        different controllers for different objects.

        For example:

        when `Ember.EXTEND_PROTOTYPES` or `Ember.EXTEND_PROTOTYPES.Function` is
        `true`, which is the default.

        Computed properties allow you to treat a function like a property:

        ```javascript
        MyApp.President = Ember.Object.extend({
          firstName: '',
          lastName:  '',

          fullName: function() {

            // Call this flag to mark the function as a property
          }.property()
        });

        var president = MyApp.President.create({
          firstName: "Barack",
          lastName: "Obama"
        });

        president.get('fullName');    // "Barack Obama"
        ```

        Treating a function like a property is useful because they can work with
        bindings, just like any other property.

        Many computed properties have dependencies on other properties. For
        example, in the above example, the `fullName` property depends on
        `firstName` and `lastName` to determine its value. You can tell Ember
        about these dependencies like this:

        ```javascript
        MyApp.President = Ember.Object.extend({
          firstName: '',
          lastName:  '',

          fullName: function() {
            return this.get('firstName') + ' ' + this.get('lastName');

            // Tell Ember.js that this computed property depends on firstName
            // and lastName
          }.property('firstName', 'lastName')
        });
        ```

        Make sure you list these dependencies so Ember knows when to update
        bindings that connect to a computed property. Changing a dependency
        will not immediately trigger an update of the computed property, but
        will instead clear the cache so that it is updated when the next `get`
        is called on the property.

        See [Ember.ComputedProperty](/api/classes/Ember.ComputedProperty.html), [Ember.computed](/api/#method_computed).

        @method property
        @for Function
      */

        var ret = computed(this);
        // ComputedProperty.prototype.property expands properties; no need for us to

        return ret.property.apply(ret, arguments);

        You can observe property changes simply by adding the `observes`

      `Ember.ActionHandler` is available on some familiar classes including
      `Ember.Route`, `Ember.View`, `Ember.Component`, and controllers such as
      `Ember.Controller` and `Ember.ObjectController`.
      (Internally the mixin is used by `Ember.CoreView`, `Ember.ControllerMixin`,
      and `Ember.Route` and available to the above classes through
      inheritance.)

      @class ActionHandler
      @namespace Ember
    */
    var ActionHandler = Mixin.create({
      mergedProperties: ['_actions'],

      /**
        The collection of functions, keyed by name, available on this
        `ActionHandler` as action targets.

        These functions will be invoked when a matching `{{action}}` is triggered
        from within a template and the application's current route is this route.

        Actions can also be invoked from other parts of your application
        via `ActionHandler#send`.

        The `actions` hash will inherit action handlers from
        the `actions` hash defined on extended parent classes
        or mixins rather than just replace the entire hash, e.g.:

        ```js
        App.CanDisplayBanner = Ember.Mixin.create({
          actions: {
            displayBanner: function(msg) {
              // ...
            }
          }
        });

        App.WelcomeRoute = Ember.Route.extend(App.CanDisplayBanner, {
          actions: {
            playMusic: function() {
              // ...
            }
          }
        });

        // `WelcomeRoute`, when active, will be able to respond
        // to both actions, since the actions hash is merged rather
        // then replaced when extending mixins / parent classes.
        this.send('displayBanner');
        this.send('playMusic');
        ```

        Within a Controller, Route, View or Component's action handler,
        the value of the `this` context is the Controller, Route, View or
        Component object:

        ```js
        App.SongRoute = Ember.Route.extend({
          actions: {
            myAction: function() {
              this.controllerFor("song");
              this.transitionTo("other.route");
              ...
            }
          }
        });
        ```

        It is also possible to call `this._super()` from within an
        action handler if it overrides a handler defined on a parent
        class or mixin:

        Take for example the following routes:

        ```js
        App.DebugRoute = Ember.Mixin.create({
          actions: {
            debugRouteInformation: function() {
              console.debug("trololo");
            }
          }
        });

        App.AnnoyingDebugRoute = Ember.Route.extend(App.DebugRoute, {
          actions: {
            debugRouteInformation: function() {
              // also call the debugRouteInformation of mixed in App.DebugRoute
              this._super();

              // show additional annoyance
              window.alert(...);
            }
          }
        });
        ```

        ## Bubbling

        By default, an action will stop bubbling once a handler defined
        on the `actions` hash handles it. To continue bubbling the action,
        you must return `true` from the handler:

        ```js
        App.Router.map(function() {
          this.resource("album", function() {
            this.route("song");
          });
        });

        App.AlbumRoute = Ember.Route.extend({
          actions: {
            startPlaying: function() {
            }
          }
        });

        App.AlbumSongRoute = Ember.Route.extend({
          actions: {
            startPlaying: function() {
              // ...

              if (actionShouldAlsoBeTriggeredOnParentRoute) {
                return true;
              }
            }
          }
        });

        bubble to the `target`. Bubbling happens when an `actionName` can

      concrete implementation, but it can be used up by other classes that want
      to appear like arrays.

      For example, ArrayProxy and ArrayController are both concrete classes that can
      be instantiated to implement array-like behavior. Both of these classes use
      the Array Mixin by way of the MutableArray mixin, which allows observable
      changes to be made to the underlying array.

      Unlike `Ember.Enumerable,` this mixin defines methods specifically for
      collections that provide index-ordered access to their contents. When you
      are designing code that needs to accept any kind of Array-like object, you
      should use these methods instead of Array primitives because these will
      properly notify observers of changes to the array.

      Although these methods are efficient, they do add a layer of indirection to
      your application so it is a good idea to use them only when you need the
      flexibility of using both true JavaScript arrays and "virtual" arrays such
      as controllers and collections.

      You can use the methods defined in this module to access and modify array
      contents in a KVO-friendly way. You can also be notified whenever the
      membership of an array changes by using `.observes('myArray.[]')`.

      To support `Ember.Array` in your own class, you must override two
      primitives to use it: `replace()` and `objectAt()`.

      Note that the Ember.Array mixin also incorporates the `Ember.Enumerable`
      mixin. All `Ember.Array`-like objects are also enumerable.

        or is greater or equal than the array length, returns `undefined`.

        This is one of the primitives you must implement to support `Ember.Array`.
        If your object supports retrieving the value of an array item using `get()`
        (i.e. `myArray.get(0)`), then you do not need to implement this method
        yourself.

      simple ground rule: Never set a controllers content, rather always set
      it's model and ember will do the right thing.

    /**
      This mixin defines the common interface implemented by enumerable objects
      in Ember. Most of these methods follow the standard Array iteration
      API defined up to JavaScript 1.8 (excluding language-specific features that
      cannot be emulated in older versions of JavaScript).

      This mixin is applied automatically to the Array class on page load, so you
      can use any of these methods on simple arrays. If Array already implements
      one of these methods, the mixin will not override them.

      ## Writing Your Own Enumerable

      To make your own custom class enumerable, you need two items:

      1. You must have a length property. This property should change whenever
         the number of items in your enumerable object changes. If you use this
         with an `Ember.Object` subclass, you should be sure to change the length
         property using `set().`

      2. You must implement `nextObject().` See documentation.

      Once you have these two methods implemented, apply the `Ember.Enumerable` mixin
      to your class and you will be able to enumerate the contents of your object
      like any other collection.

      ## Using Ember Enumeration with Other Libraries

      Many other libraries provide some kind of iterator or enumeration like
      facility. This is often where the most common API conflicts occur.
      Ember's API is designed to be as friendly as possible with other
      libraries by implementing only methods that mostly correspond to the
      JavaScript 1.8 API.

      @class Enumerable
      @namespace Ember
      @since Ember 0.9

    __exports__["default"] = Mixin.create({

      /**
        Implement this method to make your class enumerable.

        This method will be call repeatedly during enumeration. The index value
        will always begin with 0 and increment monotonically. You don't have to
        rely on the index value to determine what object to return, but you should
        always check the value and start from the beginning when you see the
        requested index is 0.

        The `previousObject` is the object that was returned from the last call
        to `nextObject` for the current iteration. This is a useful way to
        manage iteration if you are tracing a linked list, for example.

        Finally the context parameter will always contain a hash you can use as
        a "scratchpad" to maintain any other state you need in order to iterate
        properly. The context object is reused and is not reset between
        iterations so make sure you setup the context with a fresh state whenever
        the index parameter is 0.

        Generally iterators will continue to call `nextObject` until the index
        reaches the your current length-1. If you run out of data before this
        time for some reason, you should simply return undefined.

        The default implementation of this method simply looks up the index.

      The `Ember.Freezable` mixin implements some basic methods for marking an
      object as frozen. Once an object is frozen it should be read only. No changes
      may be made the internal state of the object.

      ## Enforcement

      To fully support freezing in your subclass, you must include this mixin and
      override any method that might alter any property on the object to instead
      raise an exception. You can check the state of an object by checking the
      `isFrozen` property.

      Although future versions of JavaScript may support language-level freezing
      object objects, that is not the case today. Even if an object is freezable,
      it is still technically possible to modify the object, even though it could
      break other parts of your application that do not expect a frozen object to
      change. It is, therefore, very important that you always respect the
      `isFrozen` property on all freezable objects.

      ## Example Usage

      The example below shows a simple object that implement the `Ember.Freezable`
      protocol.

      ```javascript
      Contact = Ember.Object.extend(Ember.Freezable, {
        firstName: null,
        lastName: null,

        // swaps the names
        swapNames: function() {
          if (this.get('isFrozen')) throw Ember.FROZEN_ERROR;
          var tmp = this.get('firstName');
          this.set('firstName', this.get('lastName'));
          this.set('lastName', tmp);
          return this;
        }

      });

      c = Contact.create({ firstName: "John", lastName: "Doe" });
      c.swapNames();  // returns c
      c.freeze();
      c.swapNames();  // EXCEPTION
      ```

      ## Copying

      Usually the `Ember.Freezable` protocol is implemented in cooperation with the
      `Ember.Copyable` protocol, which defines a `frozenCopy()` method that will
      return a frozen object, if the object implements this method as well.

      @class Freezable
      @namespace Ember
      @since Ember 0.9
    */
    var Freezable = Mixin.create({

      This mixin defines the API for modifying generic enumerables. These methods

      Note that an Enumerable can change even if it does not implement this mixin.
      For example, a MappedEnumerable cannot be directly modified but if its
      underlying enumerable changes, it will change also.

      ## Adding Objects

      To add an object to an enumerable, use the `addObject()` method. This
      method will only add the object to the enumerable if the object is not
      already present and is of a type supported by the enumerable.

      ```javascript
      set.addObject(contact);
      ```

      ## Removing Objects

      To remove an object from an enumerable, use the `removeObject()` method. This
      will only remove the object if it is present in the enumerable, otherwise
      this method has no effect.

      ```javascript
      set.removeObject(contact);
      ```

      ## Implementing In Your Own Code

      If you are implementing an object and want to support this API, just include
      this mixin in your class and implement the required methods. In your unit
      tests, be sure to apply the Ember.MutableEnumerableTests to your object.

    /**
      ## Overview

      This mixin provides properties and property observing functionality, core
      features of the Ember object model.

      Properties and observers allow one object to observe changes to a
      property on another object. This is one of the fundamental ways that
      models, controllers and views communicate with each other in an Ember
      application.

      Any object that has this mixin applied can be used in observer
      operations. That includes `Ember.Object` and most objects you will
      interact with as you write your Ember application.

      Note that you will not generally apply this mixin to classes yourself,
      but you will use the features provided by this module frequently, so it
      is important to understand how to use it.

      ## Using `get()` and `set()`

      Because of Ember's support for bindings and observers, you will always
      access properties using the get method, and set properties using the
      set method. This allows the observing objects to be notified and
      computed properties to be handled properly.

      More documentation about `get` and `set` are below.

      ## Observing Property Changes

      You typically observe property changes simply by adding the `observes`
      call to the end of your method declarations in classes that you write.
      For example:

      ```javascript
      Ember.Object.extend({
        valueObserver: function() {
          // Executes whenever the "value" property changes
        }.observes('value')
      });
      ```

      Although this is the most common way to add an observer, this capability
      is actually built into the `Ember.Object` class on top of two methods
      defined in this mixin: `addObserver` and `removeObserver`. You can use
      these two methods to add and remove observers yourself if you need to
      do so at runtime.

      To add an observer for a property, call:

      ```javascript
      object.addObserver('propertyKey', targetObject, targetAction)
      ```

      This will call the `targetAction` method on the `targetObject` whenever
      the value of the `propertyKey` changes.

      Note that if `propertyKey` is a computed property, the observer will be
      called when any of the property dependencies are changed, even if the
      resulting value of the computed property is unchanged. This is necessary
      because computed properties are not computed until `get` is called.

      @class Observable
      @namespace Ember
    */
    __exports__["default"] = Mixin.create({

      /**
        Retrieves the value of a property from the object.

        This method is usually similar to using `object[keyName]` or `object.keyName`,
        however it supports both computed properties and the unknownProperty
        handler.

        Because `get` unifies the syntax for accessing all these kinds
        of properties, it can make many refactorings easier, such as replacing a
        simple property with a computed property, or vice versa.

        ### Computed Properties

        Computed properties are methods defined with the `property` modifier
        declared at the end, such as:

        ```javascript
        fullName: function() {
          return this.get('firstName') + ' ' + this.get('lastName');
        }.property('firstName', 'lastName')
        ```

        When you call `get` on a computed property, the function will be
        called and the return value will be returned instead of the function
        itself.

        ### Unknown Properties

        Likewise, if you try to call `get` on a property whose value is
        `undefined`, the `unknownProperty()` method will be called on the object.
        If this method returns any value other than `undefined`, it will be returned
        instead. This allows you to implement "virtual" properties that are
        not defined upfront.

        @method get
        @param {String} keyName The property to retrieve
        @return {Object} The property value or undefined.
      */
      get: function(keyName) {
        return get(this, keyName);
      },

      /**
        To get multiple properties at once, call `getProperties`
        with a list of strings or an array:

        ```javascript
        record.getProperties('firstName', 'lastName', 'zipCode');
        // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
        ```

        is equivalent to:

        ```javascript
        record.getProperties(['firstName', 'lastName', 'zipCode']);
        // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
        ```

        @method getProperties
        @param {String...|Array} list of keys to get
        @return {Hash}
      */
      getProperties: function() {
        return apply(null, getProperties, [this].concat(slice.call(arguments)));
      },

      /**
        Sets the provided key or path to the value.

        This method is generally very similar to calling `object[key] = value` or
        `object.key = value`, except that it provides support for computed
        properties, the `setUnknownProperty()` method and property observers.

        ### Computed Properties

        If you try to set a value on a key that has a computed property handler
        defined (see the `get()` method for an example), then `set()` will call
        that method, passing both the value and key instead of simply changing
        the value itself. This is useful for those times when you need to
        implement a property that is composed of one or more member
        properties.

        ### Unknown Properties

        If you try to set a value on a key that is undefined in the target
        object, then the `setUnknownProperty()` handler will be called instead. This
        gives you an opportunity to implement complex "virtual" properties that
        are not predefined on the object. If `setUnknownProperty()` returns
        undefined, then `set()` will simply set the value on the object.

        ### Property Observers

        In addition to changing the property, `set()` will also register a property
        change with the object. Unless you have placed this call inside of a
        `beginPropertyChanges()` and `endPropertyChanges(),` any "local" observers
        (i.e. observer methods declared on the same object), will be called
        immediately. Any "remote" observers (i.e. observer methods declared on
        another object) will be placed in a queue and called at a later time in a
        coalesced manner.

        ### Chaining

        In addition to property changes, `set()` returns the value of the object
        itself so you can do chaining like this:

        ```javascript
        record.set('firstName', 'Charles').set('lastName', 'Jolley');
        ```

        @method set
        @param {String} keyName The property to set
        @param {Object} value The value to set or `null`.
        @return {Ember.Observable}
      */
      set: function(keyName, value) {
        set(this, keyName, value);
        return this;
      },


      /**
        Sets a list of properties at once. These properties are set inside
        a single `beginPropertyChanges` and `endPropertyChanges` batch, so
        observers will be buffered.

        ```javascript
        record.setProperties({ firstName: 'Charles', lastName: 'Jolley' });
        ```

        @method setProperties
        @param {Hash} hash the hash of keys and values to set
        @return {Ember.Observable}
      */
      setProperties: function(hash) {
        return setProperties(this, hash);
      },

      /**
        Adds an observer on a property.

        This is the core method used to register an observer for a property.

        Once you call this method, any time the key's value is set, your observer
        will be notified. Note that the observers are triggered any time the
        value is set, regardless of whether it has actually changed. Your
        observer should be prepared to handle that.

        You can also pass an optional context parameter to this method. The
        context will be passed to your observer method whenever it is triggered.
        Note that if you add the same target/method pair on a key multiple times
        with different context parameters, your observer will only be called once
        with the last context you passed.

        ### Observer Methods

        Observer methods you pass should generally have the following signature if
        you do not pass a `context` parameter:

        ```javascript
        fooDidChange: function(sender, key, value, rev) { };
        ```

        The sender is the object that changed. The key is the property that
        changes. The value property is currently reserved and unused. The rev
        is the last property revision of the object when it changed, which you can
        use to detect if the key value has really changed or not.

        If you pass a `context` parameter, the context will be passed before the
        revision like so:

        ```javascript
        fooDidChange: function(sender, key, value, context, rev) { };
        ```

        Usually you will not need the value, context or revision parameters at
        the end. In this case, it is common to write observer methods that take
        only a sender and key value as parameters or, if you aren't interested in
        any of these values, to write an observer that has no parameters at all.

        @method addObserver
        @param {String} key The key to observer
        @param {Object} target The target object to invoke
        @param {String|Function} method The method to invoke.

      },

      /**

      the controller has bindable attributes which
      track the promises life cycle

      ```javascript
      controller.get('isPending')   //=> true
      controller.get('isSettled')  //=> false
      controller.get('isRejected')  //=> false
      controller.get('isFulfilled') //=> false
      ```

      When the the $.getJSON completes, and the promise is fulfilled
      with json, the life cycle attributes will update accordingly.

      ```javascript
      controller.get('isPending')   //=> false
      controller.get('isSettled')   //=> true
      controller.get('isRejected')  //=> false
      controller.get('isFulfilled') //=> true
      ```

      As the controller is an ObjectController, and the json now its content,
      all the json properties will be available directly from the controller.

      ```javascript
      // Assuming the following json:
      {
        firstName: 'Stefan',
        lastName: 'Penner'
      }

      // both properties will accessible on the controller
      controller.get('firstName') //=> 'Stefan'
      controller.get('lastName')  //=> 'Penner'
      ```

      If the controller is backing a template, the attributes are
      bindable from within that template

      ```handlebars
      {{#if isPending}}
        loading...
      {{else}}
        firstName: {{firstName}}

    /**
      `Ember.SortableMixin` provides a standard interface for array proxies
      to specify a sort order and maintain this sorting when objects are added,
      removed, or updated without changing the implicit order of their underlying
      modelarray:

      ```javascript
      songs = [
        {trackNumber: 4, title: 'Ob-La-Di, Ob-La-Da'},
        {trackNumber: 2, title: 'Back in the U.S.S.R.'},
        {trackNumber: 3, title: 'Glass Onion'},
      ];

      songsController = Ember.ArrayController.create({
        model: songs,
        sortProperties: ['trackNumber'],
        sortAscending: true
      });

      songsController.get('firstObject');  // {trackNumber: 2, title: 'Back in the U.S.S.R.'}

      songsController.addObject({trackNumber: 1, title: 'Dear Prudence'});
      songsController.get('firstObject');  // {trackNumber: 1, title: 'Dear Prudence'}
      ```

      If you add or remove the properties to sort by or change the sort direction the model
      sort order will be automatically updated.

      ```javascript
      songsController.set('sortProperties', ['title']);
      songsController.get('firstObject'); // {trackNumber: 2, title: 'Back in the U.S.S.R.'}

      songsController.toggleProperty('sortAscending');
      songsController.get('firstObject'); // {trackNumber: 4, title: 'Ob-La-Di, Ob-La-Da'}
      ```

      SortableMixin works by sorting the arrangedContent array, which is the array that
      arrayProxy displays. Due to the fact that the underlying 'content' array is not changed, that
      array will not display the sorted list:

       ```javascript
      songsController.get('content').get('firstObject'); // Returns the unsorted original content
      songsController.get('firstObject'); // Returns the sorted content.
      ```

      Although the sorted content can also be accessed through the arrangedContent property,
      it is preferable to use the proxied class and not the arrangedContent array directly.

      Send an `action` with an `actionContext` to a `target`. The action, actionContext
      and target will be retrieved from properties of the object. For example:

      ```javascript
      App.SaveButtonView = Ember.View.extend(Ember.TargetActionSupport, {
        target: Ember.computed.alias('controller'),
        action: 'save',
        actionContext: Ember.computed.alias('context'),
        click: function() {
          this.triggerAction(); // Sends the `save` action, along with the current context
                                // to the current controller
        }
      });
      ```

      The `target`, `action`, and `actionContext` can be provided as properties of
      an optional object argument to `triggerAction` as well.

      ```javascript
      App.SaveButtonView = Ember.View.extend(Ember.TargetActionSupport, {
        click: function() {
          this.triggerAction({
            action: 'save',
            target: this.get('controller'),
            actionContext: this.get('context')
          }); // Sends the `save` action, along with the current context
              // to the current controller
        }
      });
      ```

      The `actionContext` defaults to the object you are mixing `TargetActionSupport` into.
      But `target` and `action` must be specified either as properties or with the argument
      to `triggerAction`, or a combination:

      ```javascript
      App.SaveButtonView = Ember.View.extend(Ember.TargetActionSupport, {
        target: Ember.computed.alias('controller'),
        click: function() {
          this.triggerAction({
            action: 'save'
          }); // Sends the `save` action, along with a reference to `this`,
              // to the current controller
        }
      });
      ```

      An ArrayProxy wraps any other object that implements `Ember.Array` and/or
      `Ember.MutableArray,` forwarding all requests. This makes it very useful for
      a number of binding use cases or other cases where being able to swap
      out the underlying array is useful.

      A simple example of usage:

      ```javascript
      var pets = ['dog', 'cat', 'fish'];
      var ap = Ember.ArrayProxy.create({ content: Ember.A(pets) });

      ap.get('firstObject');                        // 'dog'
      ap.set('content', ['amoeba', 'paramecium']);
      ap.get('firstObject');                        // 'amoeba'
      ```

      This class can also be useful as a layer to transform the contents of
      an array, as they are accessed. This can be done by overriding
      `objectAtContent`:

      ```javascript
      var pets = ['dog', 'cat', 'fish'];
      var ap = Ember.ArrayProxy.create({
          content: Ember.A(pets),
          objectAtContent: function(idx) {
              return this.get('content').objectAt(idx).toUpperCase();
          }
      });

      ap.get('firstObject'); // . 'DOG'
      ```

          name: "Steve"
        });

        // alerts 'Name is Steve'.
        ```

        NOTE: If you do override `init` for a framework class like `Ember.View` or
        `Ember.ArrayController`, be sure to call `this._super()` in your
        `init` declaration! If you don't, Ember may not have an opportunity to
        do important setup work, and you'll see strange behavior in your
        application.

        @method init
      */
      init: function() {},

      /**
        Defines the properties that will be concatenated from the superclass
        (instead of overridden).

        By default, when you extend an Ember class a property defined in
        the subclass overrides a property with the same name that is defined
        in the superclass. However, there are some cases where it is preferable
        to build up a property's value by combining the superclass' property
        value with the subclass' value. An example of this in use within Ember
        is the `classNames` property of `Ember.View`.

        Here is some sample code showing the difference between a concatenated
        property and a normal one:

        ```javascript
        App.BarView = Ember.View.extend({
          someNonConcatenatedProperty: ['bar'],
          classNames: ['bar']
        });

        App.FooBarView = App.BarView.extend({
          someNonConcatenatedProperty: ['foo'],
          classNames: ['foo']
        });

        var fooBarView = App.FooBarView.create();
        fooBarView.get('someNonConcatenatedProperty'); // ['foo']
        fooBarView.get('classNames'); // ['ember-view', 'bar', 'foo']
        ```

        This behavior extends to object creation as well. Continuing the
        above example:

        ```javascript
        var view = App.FooBarView.create({
          someNonConcatenatedProperty: ['baz'],
          classNames: ['baz']
        })
        view.get('someNonConcatenatedProperty'); // ['baz']
        view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
        ```
        Adding a single property that is not an array will just add it in the array:

        ```javascript
        var view = App.FooBarView.create({
          classNames: 'baz'
        })
        view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
        ```

        Using the `concatenatedProperties` property, we can tell to Ember that mix
        the content of the properties.

        In `Ember.View` the `classNameBindings` and `attributeBindings` properties
        are also concatenated, in addition to `classNames`.

        This feature is available for you to use throughout the Ember object model,
        although typical app developers are likely to use it infrequently. Since
        it changes expectations about behavior of properties, you should properly
        document its usage in each individual concatenated property (to not
        mislead your users to think they can override the property in a subclass).

        person = App.Person.create()
        person.toString() //=> "<App.Person:ember1024>"
        ```

        If the object's class is not defined on an Ember namespace, it will
        indicate it is a subclass of the registered superclass:

        Creates a new subclass.

        ```javascript
        App.Person = Ember.Object.extend({
          say: function(thing) {
            alert(thing);
           }
        });
        ```

        This defines a new subclass of Ember.Object: `App.Person`. It contains one method: `say()`.

        You can also create a subclass from any existing class by calling its `extend()`  method. For example, you might want to create a subclass of Ember's built-in `Ember.View` class:

        ```javascript
        App.PersonView = Ember.View.extend({
          tagName: 'li',
          classNameBindings: ['isAdministrator']
        });
        ```

        When defining a subclass, you can override methods but still access the implementation of your parent class by calling the special `_super()` method:

        ```javascript
        App.Person = Ember.Object.extend({
          say: function(thing) {
            var name = this.get('name');
            alert(name + ' says: ' + thing);
          }
        });

        App.Soldier = App.Person.extend({
          say: function(thing) {
            this._super(thing + ", sir!");
          },
          march: function(numberOfHours) {
            alert(this.get('name') + ' marches for ' + numberOfHours + ' hours.')
          }
        });

        var yehuda = App.Soldier.create({
          name: "Yehuda Katz"
        });

        yehuda.say("Yes");  // alerts "Yehuda Katz says: Yes, sir!"
        ```

        The `create()` on line #17 creates an *instance* of the `App.Soldier` class. The `extend()` on line #8 creates a *subclass* of `App.Person`. Any instance of the `App.Person` class will *not* have the `march()` method.

        You can also pass `Mixin` classes to add additional properties to the subclass.

        ```javascript
        App.Person = Ember.Object.extend({
          say: function(thing) {
            alert(this.get('name') + ' says: ' + thing);
          }
        });

        App.SingingMixin = Mixin.create({
          sing: function(thing){
            alert(this.get('name') + ' sings: la la la ' + thing);
          }
        });

        App.BroadwayStar = App.Person.extend(App.SingingMixin, {
          dance: function() {
            alert(this.get('name') + ' dances: tap tap tap tap ');
          }
        });
        ```

        The `App.BroadwayStar` class contains three methods: `say()`, `sing()`, and `dance()`.

        In other words, this creates static properties and functions for the class. These are only available on the class
        and not on any instance of that class.

        ```javascript
        App.Person = Ember.Object.extend({
          name : "",
          sayHello : function(){
            alert("Hello. My name is " + this.get('name'));
          }
        });

        App.Person.reopenClass({
          species : "Homo sapiens",
          createPerson: function(newPersonsName){
            return App.Person.create({
              name:newPersonsName
            });
          }
        });

        var tom = App.Person.create({
          name : "Tom Dale"
        });
        var yehuda = App.Person.createPerson("Yehuda Katz");

        tom.sayHello(); // "Hello. My name is Tom Dale"
        yehuda.sayHello(); // "Hello. My name is Yehuda Katz"
        alert(App.Person.species); // "Homo sapiens"
        ```

        Note that `species` and `createPerson` are *not* valid on the `tom` and `yehuda`
        variables. They are only valid on `App.Person`.

        In some cases, you may want to annotate computed properties with additional
        metadata about how they function or what values they operate on. For
        example, computed property functions may close over variables that are then
        no longer available for introspection.

        You can pass a hash of these values to a computed property like this:

        ```javascript
        person: function() {
          var personId = this.get('personId');
          return App.Person.create({ id: personId });
        }.property().meta({ type: App.Person })
        ```

        Once you've done this, you can retrieve the values saved to the computed
        property from your class like this:

        ```javascript
        MyClass.metaForProperty('person');
        ```

        This will return the original hash that was passed to `meta()`.

    /**
      An unordered collection of objects.

      A Set works a bit like an array except that its items are not ordered. You
      can create a set to efficiently test for membership for an object. You can
      also iterate through a set just like an array, even accessing objects by
      index, however there is no guarantee as to their order.

      All Sets are observable via the Enumerable Observer API - which works
      on any enumerable object including both Sets and Arrays.

      ## Creating a Set

      You can create a set like you would most objects using
      `new Ember.Set()`. Most new sets you create will be empty, but you can
      also initialize the set with some content by passing an array or other
      enumerable of objects to the constructor.

      Finally, you can pass in an existing set and the set will be copied. You
      can also create a copy of a set by calling `Ember.Set#copy()`.

      ```javascript
      // creates a new empty set
      var foundNames = new Ember.Set();

      // creates a set with four names in it.
      var names = new Ember.Set(["Charles", "Tom", "Juan", "Alex"]); // :P

      // creates a copy of the names set.
      var namesCopy = new Ember.Set(names);

      // same as above.
      var anotherNamesCopy = names.copy();
      ```

      ## Adding/Removing Objects

      You generally add or remove objects from a set using `add()` or
      `remove()`. You can add any type of object including primitives such as
      numbers, strings, and booleans.

      Unlike arrays, objects can only exist one time in a set. If you call `add()`
      on a set with the same object multiple times, the object will only be added
      once. Likewise, calling `remove()` with the same object multiple times will
      remove the object the first time and have no effect on future calls until
      you add the object to the set again.

      NOTE: You cannot add/remove `null` or `undefined` to a set. Any attempt to do
      so will be ignored.

      In addition to add/remove you can also call `push()`/`pop()`. Push behaves
      just like `add()` but `pop()`, unlike `remove()` will pick an arbitrary
      object, remove it and return it. This is a good way to use a set as a job
      queue when you don't care which order the jobs are executed in.

      ## Testing for an Object

      To test for an object's presence in a set you simply call
      `Ember.Set#contains()`.

      ## Observing changes

      When using `Ember.Set`, you can observe the `"[]"` property to be
      alerted whenever the content changes. You can also add an enumerable
      observer to the set to be notified of specific objects that are added and
      removed from the set. See [Ember.Enumerable](/api/classes/Ember.Enumerable.html)
      for more information on enumerables.

      This is often unhelpful. If you are filtering sets of objects, for instance,
      it is very inefficient to re-filter all of the items each time the set
      changes. It would be better if you could just adjust the filtered set based
      on what was changed on the original set. The same issue applies to merging
      sets, as well.

      ## Other Methods

      `Ember.Set` primary implements other mixin APIs. For a complete reference
      on the methods you will use with `Ember.Set`, please consult these mixins.
      The most useful ones will be `Ember.Enumerable` and
      `Ember.MutableEnumerable` which implement most of the common iterator
      methods you are used to on Array.

      Note that you can also use the `Ember.Copyable` and `Ember.Freezable`
      APIs on `Ember.Set` as well. Once a set is frozen it can no longer be
      modified. The benefit of this is that when you call `frozenCopy()` on it,
      Ember will avoid making copies of the set. This allows you to write
      code that can know with certainty when the underlying set data will or
      will not be modified.

        when `App.injectTestHelpers` is called.

        the first parameter.

    `Ember.ViewTargetActionSupport` is a mixin that can be included in a
    view class to add a `triggerAction` method with semantics similar to
    the Handlebars `{{action}}` helper. It provides intelligent defaults
    for the action's target: the view's controller; and the context that is
    sent with the action: the view's context.

    Note: In normal Ember usage, the `{{action}}` helper is usually the best
    choice. This mixin is most often useful when you are doing more complex
    event handling in custom View subclasses.

    For example:

    ```javascript
    App.SaveButtonView = Ember.View.extend(Ember.ViewTargetActionSupport, {
      action: 'save',
      click: function() {
        this.triggerAction(); // Sends the `save` action, along with the current context
                              // to the current controller
      }
    });

    /**
      `Ember.CollectionView` is an `Ember.View` descendent responsible for managing
      a collection (an array or array-like object) by maintaining a child view object
      and associated DOM representation for each item in the array and ensuring
      that child views and their associated rendered HTML are updated when items in
      the array are added, removed, or replaced.

      ## Setting content

      The managed collection of objects is referenced as the `Ember.CollectionView`
      instance's `content` property.

      ```javascript
      someItemsView = Ember.CollectionView.create({
        content: ['A', 'B','C']
      })
      ```

      The view for each item in the collection will have its `content` property set
      to the item.

      ## Specifying itemViewClass

      By default the view class for each item in the managed collection will be an
      instance of `Ember.View`. You can supply a different class by setting the
      `CollectionView`'s `itemViewClass` property.

      Given an empty `<body>` and the following code:

      ```javascript
      someItemsView = Ember.CollectionView.create({
        classNames: ['a-collection'],
        content: ['A','B','C'],
        itemViewClass: Ember.View.extend({
          template: Ember.Handlebars.compile("the letter: {{view.content}}")
        })
      });

      someItemsView.appendTo('body');
      ```

      Will result in the following HTML structure

      ```html
      <div class="ember-view a-collection">
        <div class="ember-view">the letter: A</div>
        <div class="ember-view">the letter: B</div>
        <div class="ember-view">the letter: C</div>
      </div>
      ```

      ## Automatic matching of parent/child tagNames

      Setting the `tagName` property of a `CollectionView` to any of
      "ul", "ol", "table", "thead", "tbody", "tfoot", "tr", or "select" will result
      in the item views receiving an appropriately matched `tagName` property.

      Given an empty `<body>` and the following code:

      ```javascript
      anUnorderedListView = Ember.CollectionView.create({
        tagName: 'ul',
        content: ['A','B','C'],
        itemViewClass: Ember.View.extend({
          template: Ember.Handlebars.compile("the letter: {{view.content}}")
        })
      });

      anUnorderedListView.appendTo('body');
      ```

      Will result in the following HTML structure

      ```html
      <ul class="ember-view a-collection">
        <li class="ember-view">the letter: A</li>
        <li class="ember-view">the letter: B</li>
        <li class="ember-view">the letter: C</li>
      </ul>
      ```

      Additional `tagName` pairs can be provided by adding to
      `Ember.CollectionView.CONTAINER_MAP `

      ```javascript
      Ember.CollectionView.CONTAINER_MAP['article'] = 'section'
      ```

      ## Programmatic creation of child views

      For cases where additional customization beyond the use of a single
      `itemViewClass` or `tagName` matching is required CollectionView's
      `createChildView` method can be overidden:

      ```javascript
      CustomCollectionView = Ember.CollectionView.extend({
        createChildView: function(viewClass, attrs) {
          if (attrs.content.kind == 'album') {
            viewClass = App.AlbumView;
          } else {
            viewClass = App.SongView;
          }
          return this._super(viewClass, attrs);
        }
      });
      ```

      ## Empty View

      You can provide an `Ember.View` subclass to the `Ember.CollectionView`
      instance as its `emptyView` property. If the `content` property of a
      `CollectionView` is set to `null` or an empty array, an instance of this view
      will be the `CollectionView`s only child.

      ```javascript
      aListWithNothing = Ember.CollectionView.create({
        classNames: ['nothing']
        content: null,
        emptyView: Ember.View.extend({
          template: Ember.Handlebars.compile("The collection is empty")
        })
      });

      aListWithNothing.appendTo('body');
      ```

      Will result in the following HTML structure

      ```html
      <div class="ember-view nothing">
        <div class="ember-view">
          The collection is empty
        </div>
      </div>
      ```

      ## Adding and Removing items

      The `childViews` property of a `CollectionView` should not be directly
      manipulated. Instead, add, remove, replace items from its `content` property.
      This will trigger appropriate changes to its rendered HTML.

    /**
      An `Ember.Component` is a view that is completely
      isolated. Property access in its templates go
      to the view object and actions are targeted at
      the view object. There is no access to the
      surrounding context or outer controller; all
      contextual information must be passed in.

      The easiest way to create an `Ember.Component` is via
      a template. If you name a template
      `components/my-foo`, you will be able to use
      `{{my-foo}}` in other templates, which will make
      an instance of the isolated component.

      ```handlebars
      {{app-profile person=currentUser}}
      ```

      ```handlebars
      <!-- app-profile template -->
      <h1>{{person.title}}</h1>
      <img {{bind-attr src=person.avatar}}>
      <p class='signature'>{{person.signature}}</p>
      ```

      You can use `yield` inside a template to
      include the **contents** of any block attached to
      the component. The block will be executed in the
      context of the surrounding context or outer controller:

      ```handlebars
      {{#app-profile person=currentUser}}
        <p>Admin mode</p>
        {{! Executed in the controller's context. }}
      {{/app-profile}}
      ```

      ```handlebars
      <!-- app-profile template -->
      <h1>{{person.title}}</h1>
      {{! Executed in the components context. }}
      {{yield}} {{! block contents }}
      ```

      If you want to customize the component, in order to
      handle events or actions, you implement a subclass
      of `Ember.Component` named after the name of the
      component. Note that `Component` needs to be appended to the name of
      your subclass like `AppProfileComponent`.

      For example, you could implement the action
      `hello` for the `app-profile` component:

      ```javascript
      App.AppProfileComponent = Ember.Component.extend({
        actions: {
          hello: function(name) {
            console.log("Hello", name);
          }
        }
      });
      ```

      And then use it in the component's template:

      ```handlebars
      <!-- app-profile template -->

      <h1>{{person.title}}</h1>
      {{yield}} <!-- block contents -->

      <button {{action 'hello' person.name}}>
        Say Hello to {{person.name}}
      </button>
      ```

      Components must have a `-` in their name to avoid
      conflicts with built-in controls that wrap HTML
      elements. This is consistent with the same
      requirement in web components.

      @class Component
      @namespace Ember

      /**
        Triggers a named action on the controller context where the component is used if
        this controller has registered for notifications of the action.

        For example a component for playing or pausing music may translate click events
        into action notifications of "play" or "stop" depending on some internal state
        of the component:


        ```javascript
        App.PlayButtonComponent = Ember.Component.extend({
          click: function(){
            if (this.get('isPlaying')) {
              this.sendAction('play');
            } else {
              this.sendAction('stop');
            }
          }
        });
        ```

        When used inside a template these component actions are configured to
        trigger actions in the outer application context:

        ```handlebars
        {{! application.hbs }}
        {{play-button play="musicStarted" stop="musicStopped"}}
        ```

        When the component receives a browser `click` event it translate this
        interaction into application-specific semantics ("play" or "stop") and
        triggers the specified action name on the controller for the template
        where the component is used:


        ```javascript
        App.ApplicationController = Ember.Controller.extend({
          actions: {
            musicStarted: function(){
              // called when the play button is clicked
              // and the music started playing
            },
            musicStopped: function(){
              // called when the play button is clicked
              // and the music stopped playing
            }
          }
        });
        ```

        If no action name is passed to `sendAction` a default name of "action"
        is assumed.

        ```javascript
        App.NextButtonComponent = Ember.Component.extend({
          click: function(){
            this.sendAction();
          }
        });
        ```

        ```handlebars
        {{! application.hbs }}
        {{next-button action="playNextSongInAlbum"}}
        ```

      A `ContainerView` is an `Ember.View` subclass that implements `Ember.MutableArray`
      allowing programmatic management of its child views.

      ## Setting Initial Child Views

      The initial array of child views can be set in one of two ways. You can
      provide a `childViews` property at creation time that contains instance of
      `Ember.View`:

      ```javascript
      aContainer = Ember.ContainerView.create({
        childViews: [Ember.View.create(), Ember.View.create()]
      });
      ```

      You can also provide a list of property names whose values are instances of
      `Ember.View`:

      ```javascript
      aContainer = Ember.ContainerView.create({
        childViews: ['aView', 'bView', 'cView'],
        aView: Ember.View.create(),
        bView: Ember.View.create(),
        cView: Ember.View.create()
      });
      ```

      The two strategies can be combined:

      ```javascript
      aContainer = Ember.ContainerView.create({
        childViews: ['aView', Ember.View.create()],
        aView: Ember.View.create()
      });
      ```

      Each child view's rendering will be inserted into the container's rendered
      HTML in the same order as its position in the `childViews` property.

      ## Adding and Removing Child Views

      The container view implements `Ember.MutableArray` allowing programmatic management of its child views.

      To remove a view, pass that view into a `removeObject` call on the container view.

      Given an empty `<body>` the following code

      ```javascript
      aContainer = Ember.ContainerView.create({
        classNames: ['the-container'],
        childViews: ['aView', 'bView'],
        aView: Ember.View.create({
          template: Ember.Handlebars.compile("A")
        }),
        bView: Ember.View.create({
          template: Ember.Handlebars.compile("B")
        })
      });

      aContainer.appendTo('body');
      ```

      Results in the HTML

      ```html
      <div class="ember-view the-container">
        <div class="ember-view">A</div>
        <div class="ember-view">B</div>
      </div>
      ```

      Removing a view

      ```javascript
      aContainer.toArray();  // [aContainer.aView, aContainer.bView]
      aContainer.removeObject(aContainer.get('bView'));
      aContainer.toArray();  // [aContainer.aView]
      ```

      Will result in the following HTML

      ```html
      <div class="ember-view the-container">
        <div class="ember-view">A</div>
      </div>
      ```

      Similarly, adding a child view is accomplished by adding `Ember.View` instances to the
      container view.

      Given an empty `<body>` the following code

      ```javascript
      aContainer = Ember.ContainerView.create({
        classNames: ['the-container'],
        childViews: ['aView', 'bView'],
        aView: Ember.View.create({
          template: Ember.Handlebars.compile("A")
        }),
        bView: Ember.View.create({
          template: Ember.Handlebars.compile("B")
        })
      });

      aContainer.appendTo('body');
      ```

      Results in the HTML

      ```html
      <div class="ember-view the-container">
        <div class="ember-view">A</div>
        <div class="ember-view">B</div>
      </div>
      ```

      Adding a view

      ```javascript
      AnotherViewClass = Ember.View.extend({
        template: Ember.Handlebars.compile("Another view")
      });

      aContainer.toArray();  // [aContainer.aView, aContainer.bView]
      aContainer.pushObject(AnotherViewClass.create());
      aContainer.toArray(); // [aContainer.aView, aContainer.bView, <AnotherViewClass instance>]
      ```

      Will result in the following HTML

      ```html
      <div class="ember-view the-container">
        <div class="ember-view">A</div>
        <div class="ember-view">B</div>
        <div class="ember-view">Another view</div>
      </div>
      ```

      ## Templates and Layout

      A `template`, `templateName`, `defaultTemplate`, `layout`, `layoutName` or
      `defaultLayout` property on a container view will not result in the template
      or layout being rendered. The HTML contents of a `Ember.ContainerView`'s DOM
      representation will only be the rendered HTML of its child views.

      `Ember.View` is the class in Ember responsible for encapsulating templates of
      HTML content, combining templates with data to render as sections of a page's
      DOM, and registering and responding to user-initiated events.

      ## HTML Tag

      The default HTML tag name used for a view's DOM representation is `div`. This
      can be customized by setting the `tagName` property. The following view
      class:

      ```javascript
      ParagraphView = Ember.View.extend({
        tagName: 'em'
      });
      ```

      Would result in instances with the following HTML:

      ```html
      <em id="ember1" class="ember-view"></em>
      ```

      ## HTML `class` Attribute

      The HTML `class` attribute of a view's tag can be set by providing a
      `classNames` property that is set to an array of strings:

      ```javascript
      MyView = Ember.View.extend({
        classNames: ['my-class', 'my-other-class']
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view my-class my-other-class"></div>
      ```

      `class` attribute values can also be set by providing a `classNameBindings`
      property set to an array of properties names for the view. The return value
      of these properties will be added as part of the value for the view's `class`
      attribute. These properties can be computed properties:

      ```javascript
      MyView = Ember.View.extend({
        classNameBindings: ['propertyA', 'propertyB'],
        propertyA: 'from-a',
        propertyB: function() {
          if (someLogic) { return 'from-b'; }
        }.property()
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view from-a from-b"></div>
      ```

      If the value of a class name binding returns a boolean the property name
      itself will be used as the class name if the property is true. The class name
      will not be added if the value is `false` or `undefined`.

      ```javascript
      MyView = Ember.View.extend({
        classNameBindings: ['hovered'],
        hovered: true
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view hovered"></div>
      ```

      When using boolean class name bindings you can supply a string value other
      than the property name for use as the `class` HTML attribute by appending the
      preferred value after a ":" character when defining the binding:

      ```javascript
      MyView = Ember.View.extend({
        classNameBindings: ['awesome:so-very-cool'],
        awesome: true
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view so-very-cool"></div>
      ```

      Boolean value class name bindings whose property names are in a
      camelCase-style format will be converted to a dasherized format:

      ```javascript
      MyView = Ember.View.extend({
        classNameBindings: ['isUrgent'],
        isUrgent: true
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view is-urgent"></div>
      ```

      Class name bindings can also refer to object values that are found by
      traversing a path relative to the view itself:

      ```javascript
      MyView = Ember.View.extend({
        classNameBindings: ['messages.empty']
        messages: Ember.Object.create({
          empty: true
        })
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view empty"></div>
      ```

      If you want to add a class name for a property which evaluates to true and
      and a different class name if it evaluates to false, you can pass a binding
      like this:

      ```javascript
      // Applies 'enabled' class when isEnabled is true and 'disabled' when isEnabled is false
      Ember.View.extend({
        classNameBindings: ['isEnabled:enabled:disabled']
        isEnabled: true
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view enabled"></div>
      ```

      When isEnabled is `false`, the resulting HTML reprensentation looks like
      this:

      ```html
      <div id="ember1" class="ember-view disabled"></div>
      ```

      This syntax offers the convenience to add a class if a property is `false`:

      ```javascript
      // Applies no class when isEnabled is true and class 'disabled' when isEnabled is false
      Ember.View.extend({
        classNameBindings: ['isEnabled::disabled']
        isEnabled: true
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view"></div>
      ```

      When the `isEnabled` property on the view is set to `false`, it will result
      in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view disabled"></div>
      ```

      Updates to the the value of a class name binding will result in automatic
      update of the  HTML `class` attribute in the view's rendered HTML
      representation. If the value becomes `false` or `undefined` the class name
      will be removed.

      Both `classNames` and `classNameBindings` are concatenated properties. See
      [Ember.Object](/api/classes/Ember.Object.html) documentation for more
      information about concatenated properties.

      ## HTML Attributes

      The HTML attribute section of a view's tag can be set by providing an
      `attributeBindings` property set to an array of property names on the view.
      The return value of these properties will be used as the value of the view's
      HTML associated attribute:

      ```javascript
      AnchorView = Ember.View.extend({
        tagName: 'a',
        attributeBindings: ['href'],
        href: 'http://google.com'
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <a id="ember1" class="ember-view" href="http://google.com"></a>
      ```

      One property can be mapped on to another by placing a ":" between
      the source property and the destination property:

      ```javascript
      AnchorView = Ember.View.extend({
        tagName: 'a',
        attributeBindings: ['url:href'],
        url: 'http://google.com'
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <a id="ember1" class="ember-view" href="http://google.com"></a>
      ```

      If the return value of an `attributeBindings` monitored property is a boolean
      the property will follow HTML's pattern of repeating the attribute's name as
      its value:

      ```javascript
      MyTextInput = Ember.View.extend({
        tagName: 'input',
        attributeBindings: ['disabled'],
        disabled: true
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <input id="ember1" class="ember-view" disabled="disabled" />
      ```

      `attributeBindings` can refer to computed properties:

      ```javascript
      MyTextInput = Ember.View.extend({
        tagName: 'input',
        attributeBindings: ['disabled'],
        disabled: function() {
          if (someLogic) {
            return true;
          } else {
            return false;
          }
        }.property()
      });
      ```

      Updates to the the property of an attribute binding will result in automatic
      update of the  HTML attribute in the view's rendered HTML representation.

      `attributeBindings` is a concatenated property. See [Ember.Object](/api/classes/Ember.Object.html)
      documentation for more information about concatenated properties.

      ## Templates

      The HTML contents of a view's rendered representation are determined by its
      template. Templates can be any function that accepts an optional context
      parameter and returns a string of HTML that will be inserted within the
      view's tag. Most typically in Ember this function will be a compiled
      `Ember.Handlebars` template.

      ```javascript
      AView = Ember.View.extend({
        template: Ember.Handlebars.compile('I am the template')
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view">I am the template</div>
      ```

      Within an Ember application is more common to define a Handlebars templates as
      part of a page:

      ```html
      <script type='text/x-handlebars' data-template-name='some-template'>
        Hello
      </script>
      ```

      And associate it by name using a view's `templateName` property:

      ```javascript
      AView = Ember.View.extend({
        templateName: 'some-template'
      });
      ```

      If you have nested resources, your Handlebars template will look like this:

      ```html
      <script type='text/x-handlebars' data-template-name='posts/new'>
        <h1>New Post</h1>
      </script>
      ```

      And `templateName` property:

      ```javascript
      AView = Ember.View.extend({
        templateName: 'posts/new'
      });
      ```

      Using a value for `templateName` that does not have a Handlebars template
      with a matching `data-template-name` attribute will throw an error.

      For views classes that may have a template later defined (e.g. as the block
      portion of a `{{view}}` Handlebars helper call in another template or in
      a subclass), you can provide a `defaultTemplate` property set to compiled
      template function. If a template is not later provided for the view instance
      the `defaultTemplate` value will be used:

      ```javascript
      AView = Ember.View.extend({
        defaultTemplate: Ember.Handlebars.compile('I was the default'),
        template: null,
        templateName: null
      });
      ```

      Will result in instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view">I was the default</div>
      ```

      If a `template` or `templateName` is provided it will take precedence over
      `defaultTemplate`:

      ```javascript
      AView = Ember.View.extend({
        defaultTemplate: Ember.Handlebars.compile('I was the default')
      });

      aView = AView.create({
        template: Ember.Handlebars.compile('I was the template, not default')
      });
      ```

      Will result in the following HTML representation when rendered:

      ```html
      <div id="ember1" class="ember-view">I was the template, not default</div>
      ```

      ## View Context

      The default context of the compiled template is the view's controller:

      ```javascript
      AView = Ember.View.extend({
        template: Ember.Handlebars.compile('Hello {{excitedGreeting}}')
      });

      aController = Ember.Object.create({
        firstName: 'Barry',
        excitedGreeting: function() {
          return this.get("content.firstName") + "!!!"
        }.property()
      });

      aView = AView.create({
        controller: aController
      });
      ```

      Will result in an HTML representation of:

      ```html
      <div id="ember1" class="ember-view">Hello Barry!!!</div>
      ```

      A context can also be explicitly supplied through the view's `context`
      property. If the view has neither `context` nor `controller` properties, the
      `parentView`'s context will be used.

      ## Layouts

      Views can have a secondary template that wraps their main template. Like
      primary templates, layouts can be any function that  accepts an optional
      context parameter and returns a string of HTML that will be inserted inside
      view's tag. Views whose HTML element is self closing (e.g. `<input />`)
      cannot have a layout and this property will be ignored.

      Most typically in Ember a layout will be a compiled `Ember.Handlebars`
      template.

      A view's layout can be set directly with the `layout` property or reference
      an existing Handlebars template by name with the `layoutName` property.

      A template used as a layout must contain a single use of the Handlebars
      `{{yield}}` helper. The HTML contents of a view's rendered `template` will be
      inserted at this location:

      ```javascript
      AViewWithLayout = Ember.View.extend({
        layout: Ember.Handlebars.compile("<div class='my-decorative-class'>{{yield}}</div>"),
        template: Ember.Handlebars.compile("I got wrapped")
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view">
        <div class="my-decorative-class">
          I got wrapped
        </div>
      </div>
      ```

      See [Ember.Handlebars.helpers.yield](/api/classes/Ember.Handlebars.helpers.html#method_yield)
      for more information.

      ## Responding to Browser Events

      Views can respond to user-initiated events in one of three ways: method
      implementation, through an event manager, and through `{{action}}` helper use
      in their template or layout.

      ### Method Implementation

      Views can respond to user-initiated events by implementing a method that
      matches the event name. A `jQuery.Event` object will be passed as the
      argument to this method.

      ```javascript
      AView = Ember.View.extend({
        click: function(event) {
          // will be called when when an instance's
          // rendered element is clicked
        }
      });
      ```

      ### Event Managers

      Views can define an object as their `eventManager` property. This object can
      then implement methods that match the desired event names. Matching events
      that occur on the view's rendered HTML or the rendered HTML of any of its DOM
      descendants will trigger this method. A `jQuery.Event` object will be passed
      as the first argument to the method and an  `Ember.View` object as the
      second. The `Ember.View` will be the view whose rendered HTML was interacted
      with. This may be the view with the `eventManager` property or one of its
      descendent views.

      ```javascript
      AView = Ember.View.extend({
        eventManager: Ember.Object.create({
          doubleClick: function(event, view) {
            // will be called when when an instance's
            // rendered element or any rendering
            // of this views's descendent
            // elements is clicked
          }
        })
      });
      ```

      An event defined for an event manager takes precedence over events of the
      same name handled through methods on the view.

      ```javascript
      AView = Ember.View.extend({
        mouseEnter: function(event) {
          // will never trigger.
        },
        eventManager: Ember.Object.create({
          mouseEnter: function(event, view) {
            // takes precedence over AView#mouseEnter
          }
        })
      });
      ```

      Similarly a view's event manager will take precedence for events of any views
      rendered as a descendent. A method name that matches an event name will not
      be called if the view instance was rendered inside the HTML representation of
      a view that has an `eventManager` property defined that handles events of the
      name. Events not handled by the event manager will still trigger method calls
      on the descendent.

      ```javascript
      OuterView = Ember.View.extend({
        template: Ember.Handlebars.compile("outer {{#view InnerView}}inner{{/view}} outer"),
        eventManager: Ember.Object.create({
          mouseEnter: function(event, view) {
            // view might be instance of either
            // OuterView or InnerView depending on
            // where on the page the user interaction occured
          }
        })
      });

      InnerView = Ember.View.extend({
        click: function(event) {
          // will be called if rendered inside
          // an OuterView because OuterView's
          // eventManager doesn't handle click events
        },
        mouseEnter: function(event) {
          // will never be called if rendered inside
          // an OuterView.
        }
      });
      ```

      ### Handlebars `{{action}}` Helper

      See [Handlebars.helpers.action](/api/classes/Ember.Handlebars.helpers.html#method_action).

      ### Event Names

      All of the event handling approaches described above respond to the same set
      of events. The names of the built-in events are listed below. (The hash of
      built-in events exists in `Ember.EventDispatcher`.) Additional, custom events
      can be registered by using `Ember.Application.customEvents`.

      Touch events:

      * `touchStart`
      * `touchMove`
      * `touchEnd`
      * `touchCancel`

      Keyboard events

      * `keyDown`
      * `keyUp`
      * `keyPress`

      Mouse events

      * `mouseDown`
      * `mouseUp`
      * `contextMenu`
      * `click`
      * `doubleClick`
      * `mouseMove`
      * `focusIn`
      * `focusOut`
      * `mouseEnter`
      * `mouseLeave`

      Form events:

      * `submit`
      * `change`
      * `focusIn`
      * `focusOut`
      * `input`

      HTML5 drag and drop events:

      * `dragStart`
      * `drag`
      * `dragEnter`
      * `dragLeave`
      * `dragOver`
      * `dragEnd`
      * `drop`

      ## Handlebars `{{view}}` Helper

      Other `Ember.View` instances can be included as part of a view's template by
      using the `{{view}}` Handlebars helper. See [Ember.Handlebars.helpers.view](/api/classes/Ember.Handlebars.helpers.html#method_view)
      for additional information.

      This function is called when transitioning from one URL to
      another to determine which handlers are no longer active,
      which handlers are newly active, and which handlers remain
      active but have their context changed.

      Take a list of old handlers and new handlers and partition
      them into four buckets:

      * unchanged: the handler was active in both the old and
        new URL, and its context remains the same
      * updated context: the handler was active in both the
        old and new URL, but its context changed. The handler's
        `setup` method, if any, will be called with the new
        context.
      * exited: the handler was active in the old URL, but is
        no longer active.
      * entered: the handler was not active in the old URL, but
        is now active.

      The PartitionedHandlers structure has four fields:

      * `updatedContext`: a list of `HandlerInfo` objects that
        represent handlers that remain active but have a changed
        context
      * `entered`: a list of `HandlerInfo` objects that represent
        handlers that are newly active
      * `exited`: a list of `HandlerInfo` objects that are no
        longer active.
      * `unchanged`: a list of `HanderInfo` objects that remain active.

      @param {Array[HandlerInfo]} oldHandlers a list of the handler
        information for the previous URL (or `[]` if this is the
        first handled transition)

      `RSVP.allSettled` is similar to `RSVP.all`, but instead of implementing
      a fail-fast method, it waits until all the promises have returned and
      shows you all the results. This is useful if you want to handle multiple
      promises' failure states together as a set.

      Returns a promise that is fulfilled when all the given promises have been
      settled. The return promise is fulfilled with an array of the states of
      the promises passed into the `promises` array argument.

      Each state object will either indicate fulfillment or rejection, and
      provide the corresponding value or reason. The states will take one of
      the following formats:

      ```javascript
      { state: 'fulfilled', value: value }
        or
      { state: 'rejected', reason: reason }
      ```

      Example:

      ```javascript
      var promise1 = RSVP.Promise.resolve(1);
      var promise2 = RSVP.Promise.reject(new Error('2'));
      var promise3 = RSVP.Promise.reject(new Error('3'));

        //   { state: 'rejected', reason: Error }
        // ]
        // Note that for the second item, reason.message will be '2', and for the
        // third item, reason.message will be '3'.
      }, function(error) {

      `RSVP.defer` returns an object similar to jQuery's `$.Deferred`.
      `RSVP.defer` should be used when porting over code reliant on `$.Deferred`'s
      interface. New code should use the `RSVP.Promise` constructor instead.

      The object returned from `RSVP.defer` is a plain object with three properties:

      * promise - an `RSVP.Promise`.
      * reject - a function that causes the `promise` property on this object to
        become rejected
      * resolve - a function that causes the `promise` property on this object to
        become fulfilled.

      Example:

       ```javascript
       var deferred = RSVP.defer();

       deferred.resolve("Success!");

       defered.promise.then(function(value){

     `RSVP.filter` is similar to JavaScript's native `filter` method, except that it
      waits for all promises to become fulfilled before running the `filterFn` on
      each item in given to `promises`. `RSVP.filter` returns a promise that will
      become fulfilled with the result of running `filterFn` on the values the
      promises become fulfilled with.

      For example:

      ```javascript

      var promise1 = RSVP.resolve(1);
      var promise2 = RSVP.resolve(2);
      var promise3 = RSVP.resolve(3);

      var promises = [promise1, promise2, promise3];

      var filterFn = function(item){
        return item > 1;
      };

      RSVP.filter(promises, filterFn).then(function(result){
        // result is [ 2, 3 ]
      });
      ```

      If any of the `promises` given to `RSVP.filter` are rejected, the first promise
      that is rejected will be given as an argument to the returned promise's
      rejection handler. For example:

      ```javascript
      var promise1 = RSVP.resolve(1);
      var promise2 = RSVP.reject(new Error('2'));
      var promise3 = RSVP.reject(new Error('3'));
      var promises = [ promise1, promise2, promise3 ];

      var filterFn = function(item){
        return item > 1;
      };

      RSVP.filter(promises, filterFn).then(function(array){
        // Code here never runs because there are rejected promises!
      }, function(reason) {
        // reason.message === '2'
      });
      ```

      `RSVP.filter` will also wait for any promises returned from `filterFn`.
      For instance, you may want to fetch a list of users then return a subset
      of those users based on some asynchronous operation:

      ```javascript

      var alice = { name: 'alice' };
      var bob   = { name: 'bob' };
      var users = [ alice, bob ];

      var promises = users.map(function(user){
        return RSVP.resolve(user);
      });

      var filterFn = function(user){
        // Here, Alice has permissions to create a blog post, but Bob does not.
        return getPrivilegesForUser(user).then(function(privs){
          return privs.can_create_blog_post === true;
        });
      };
      RSVP.filter(promises, filterFn).then(function(users){
        // true, because the server told us only Alice can create a blog post.
        users.length === 1;
        // false, because Alice is the only user present in `users`
        users[0] === bob;
      });
      ```

      `RSVP.hashSettled` is similar to `RSVP.allSettled`, but takes an object
      instead of an array for its `promises` argument.

      Unlike `RSVP.all` or `RSVP.hash`, which implement a fail-fast method,
      but like `RSVP.allSettled`, `hashSettled` waits until all the
      constituent promises have returned and then shows you all the results
      with their states and values/reasons. This is useful if you want to
      handle multiple promises' failure states together as a set.

      Returns a promise that is fulfilled when all the given promises have been
      settled, or rejected if the passed parameters are invalid.

      The returned promise is fulfilled with a hash that has the same key names as
      the `promises` object argument. If any of the values in the object are not
      promises, they will be copied over to the fulfilled object and marked with state
      'fulfilled'.

      Example:

      ```javascript
      var promises = {
        myPromise: RSVP.Promise.resolve(1),
        yourPromise: RSVP.Promise.resolve(2),
        theirPromise: RSVP.Promise.resolve(3),
        notAPromise: 4
      };

      RSVP.hashSettled(promises).then(function(hash){
        // hash here is an object that looks like:
        // {
        //   myPromise: { state: 'fulfilled', value: 1 },
        //   yourPromise: { state: 'fulfilled', value: 2 },
        //   theirPromise: { state: 'fulfilled', value: 3 },
        //   notAPromise: { state: 'fulfilled', value: 4 }
        // }
      });
      ```

      If any of the `promises` given to `RSVP.hash` are rejected, the state will
      be set to 'rejected' and the reason for rejection provided.

      Example:

      ```javascript
      var promises = {
        myPromise: RSVP.Promise.resolve(1),
        rejectedPromise: RSVP.Promise.reject(new Error('rejection')),
        anotherRejectedPromise: RSVP.Promise.reject(new Error('more rejection')),
      };

      RSVP.hashSettled(promises).then(function(hash){
        // hash here is an object that looks like:
        // {
        //   myPromise:              { state: 'fulfilled', value: 1 },
        //   rejectedPromise:        { state: 'rejected', reason: Error },
        //   anotherRejectedPromise: { state: 'rejected', reason: Error },
        // }
        // Note that for rejectedPromise, reason.message == 'rejection',
        // and for anotherRejectedPromise, reason.message == 'more rejection'.
      });
      ```

      An important note: `RSVP.hashSettled` is intended for plain JavaScript objects that
      are just a set of keys and values. `RSVP.hashSettled` will NOT preserve prototype
      chains.

      Example:

      ```javascript
      function MyConstructor(){
        this.example = RSVP.Promise.resolve('Example');
      }

      MyConstructor.prototype = {
        protoProperty: RSVP.Promise.resolve('Proto Property')
      };

      var myObject = new MyConstructor();

      RSVP.hashSettled(myObject).then(function(hash){
        // protoProperty will not be present, instead you will just have an
        // object that looks like:
        // {
        //   example: { state: 'fulfilled', value: 'Example' }
        // }
        //
        // hash.hasOwnProperty('protoProperty'); // false
        // 'undefined' === typeof hash.protoProperty
      });

      Example:

      ```javascript
      function MyConstructor(){
        this.example = RSVP.resolve('Example');
      }

      MyConstructor.prototype = {
        protoProperty: RSVP.resolve('Proto Property')
      };

      var myObject = new MyConstructor();

      RSVP.hash(myObject).then(function(hash){
        // protoProperty will not be present, instead you will just have an
        // object that looks like:
        // {
        //   example: 'Example'
        // }
        //
        // hash.hasOwnProperty('protoProperty'); // false
        // 'undefined' === typeof hash.protoProperty
      });
      ```

     `RSVP.map` is similar to JavaScript's native `map` method, except that it
      waits for all promises to become fulfilled before running the `mapFn` on
      each item in given to `promises`. `RSVP.map` returns a promise that will
      become fulfilled with the result of running `mapFn` on the values the promises
      become fulfilled with.

      For example:

      ```javascript

      var promise1 = RSVP.resolve(1);
      var promise2 = RSVP.resolve(2);
      var promise3 = RSVP.resolve(3);
      var promises = [ promise1, promise2, promise3 ];

      var mapFn = function(item){
        return item + 1;
      };

      RSVP.map(promises, mapFn).then(function(result){
        // result is [ 2, 3, 4 ]
      });
      ```

      If any of the `promises` given to `RSVP.map` are rejected, the first promise
      that is rejected will be given as an argument to the returned promise's
      rejection handler. For example:

      ```javascript
      var promise1 = RSVP.resolve(1);
      var promise2 = RSVP.reject(new Error('2'));
      var promise3 = RSVP.reject(new Error('3'));
      var promises = [ promise1, promise2, promise3 ];

      var mapFn = function(item){
        return item + 1;
      };

      RSVP.map(promises, mapFn).then(function(array){
        // Code here never runs because there are rejected promises!
      }, function(reason) {
        // reason.message === '2'
      });
      ```

      `RSVP.map` will also wait if a promise is returned from `mapFn`. For example,
      say you want to get all comments from a set of blog posts, but you need
      the blog posts first because they contain a url to those comments.

      ```javscript

      var mapFn = function(blogPost){
        // getComments does some ajax and returns an RSVP.Promise that is fulfilled
        // with some comments data
        return getComments(blogPost.comments_url);
      };

      // getBlogPosts does some ajax and returns an RSVP.Promise that is fulfilled
      // with some blog post data
      RSVP.map(getBlogPosts(), mapFn).then(function(comments){
        // comments is the result of asking the server for the comments
        // of all blog posts returned from getBlogPosts()
      });
      ```

    /**
      `RSVP.denodeify` takes a 'node-style' function and returns a function that
      will return an `RSVP.Promise`. You can use `denodeify` in Node.js or the
      browser when you'd prefer to use promises over using callbacks. For example,
      `denodeify` transforms the following:

      ```javascript
      var fs = require('fs');

      fs.readFile('myfile.txt', function(err, data){
        if (err) return handleError(err);
        handleData(data);
      });
      ```

      into:

      ```javascript
      var fs = require('fs');
      var readFile = RSVP.denodeify(fs.readFile);

      readFile('myfile.txt').then(handleData, handleError);
      ```

      If the node function has multiple success parameters, then `denodeify`
      just returns the first one:

      ```javascript
      var request = RSVP.denodeify(require('request'));

      request('http://example.com').then(function(res) {
        // ...
      });
      ```

      However, if you need all success parameters, setting `denodeify`'s
      second parameter to `true` causes it to return all success parameters
      as an array:

      ```javascript
      var request = RSVP.denodeify(require('request'), true);

      request('http://example.com').then(function(result) {
        // result[0] -> res
        // result[1] -> body
      });
      ```

      Or if you pass it an array with names it returns the parameters as a hash:

      ```javascript
      var request = RSVP.denodeify(require('request'), ['res', 'body']);

      request('http://example.com').then(function(result) {
        // result.res
        // result.body
      });
      ```

      Sometimes you need to retain the `this`:

      ```javascript
      var app = require('express')();
      var render = RSVP.denodeify(app.render.bind(app));
      ```

      The denodified function inherits from the original function. It works in all
      environments, except IE 10 and below. Consequently all properties of the original
      function are available to you. However, any properties you change on the
      denodeified function won't be changed on the original function. Example:

      ```javascript
      var request = RSVP.denodeify(require('request')),
          cookieJar = request.jar(); // <- Inheritance is used here

      request('http://example.com', {jar: cookieJar}).then(function(res) {
        // cookieJar.cookies holds now the cookies returned by example.com
      });
      ```

      Using `denodeify` makes it easier to compose asynchronous operations instead
      of using callbacks. For example, instead of:

      ```javascript
      var fs = require('fs');

      fs.readFile('myfile.txt', function(err, data){
        if (err) { ... } // Handle error
        fs.writeFile('myfile2.txt', data, function(err){
          if (err) { ... } // Handle error
          console.log('done')
        });
      });
      ```

      you can chain the operations together using `then` from the returned promise:

      ```javascript
      var fs = require('fs');
      var readFile = RSVP.denodeify(fs.readFile);
      var writeFile = RSVP.denodeify(fs.writeFile);

      readFile('myfile.txt').then(function(data){
        return writeFile('myfile2.txt', data);
      }).then(function(){
        console.log('done')
      }).catch(function(error){
        // Handle error
      });
      ```

      @method denodeify
      @static
      @for RSVP
      @param {Function} nodeFunc a 'node-style' function that takes a callback as
      its last argument. The callback expects an error to be passed as its first
      argument (if an error occurred, otherwise null), and the value from the
      operation as its second argument ('function(err, value){ }').
      @param {Boolean|Array} argumentNames An optional paramter that if set
      to `true` causes the promise to fulfill with the callback's success arguments
      as an array. This is useful if the node function has multiple success
      paramters. If you set this paramter to an array with names, the promise will
      fulfill with a hash with these names as keys and the success parameters as
      values.

    /**
      Promise objects represent the eventual result of an asynchronous operation. The
      primary way of interacting with a promise is through its `then` method, which
      registers callbacks to receive either a promise’s eventual value or the reason
      why the promise cannot be fulfilled.

      Terminology
      -----------

      - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
      - `thenable` is an object or function that defines a `then` method.
      - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
      - `exception` is a value that is thrown using the throw statement.
      - `reason` is a value that indicates why a promise was rejected.
      - `settled` the final resting state of a promise, fulfilled or rejected.

      A promise can be in one of three states: pending, fulfilled, or rejected.

      Promises that are fulfilled have a fulfillment value and are in the fulfilled
      state.  Promises that are rejected have a rejection reason and are in the
      rejected state.  A fulfillment value is never a thenable.

      Promises can also be said to *resolve* a value.  If this value is also a
      promise, then the original promise's settled state will match the value's
      settled state.  So a promise that *resolves* a promise that rejects will
      itself reject, and a promise that *resolves* a promise that fulfills will
      itself fulfill.


      Basic Usage:
      ------------

      ```js
      var promise = new Promise(function(resolve, reject) {
        // on success
        resolve(value);

        // on failure
        reject(reason);
      });

      promise.then(function(value) {
        // on fulfillment
      }, function(reason) {
        // on rejection
      });
      ```

      Advanced Usage:
      ---------------

      Promises shine when abstracting away asynchronous interactions such as
      `XMLHttpRequest`s.

      ```js
      function getJSON(url) {
        return new Promise(function(resolve, reject){
          var xhr = new XMLHttpRequest();

          xhr.open('GET', url);
          xhr.onreadystatechange = handler;
          xhr.responseType = 'json';
          xhr.setRequestHeader('Accept', 'application/json');
          xhr.send();

          function handler() {
            if (this.readyState === this.DONE) {
              if (this.status === 200) {
                resolve(this.response);
              } else {
                reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));
              }
            }
          };
        });
      }

      getJSON('/posts.json').then(function(json) {
        // on fulfillment
      }, function(reason) {
        // on rejection
      });
      ```

      Unlike callbacks, promises are great composable primitives.

      ```js
      Promise.all([
        getJSON('/posts'),
        getJSON('/comments')
      ]).then(function(values){
        values[0] // => postsJSON
        values[1] // => commentsJSON

        return values;
      });
      ```

      @class RSVP.Promise

    /**
      The primary way of interacting with a promise is through its `then` method,
      which registers callbacks to receive either a promise's eventual value or the
      reason why the promise cannot be fulfilled.

      ```js
      findUser().then(function(user){
        // user is available
      }, function(reason){
        // user is unavailable, and you are given the reason why
      });
      ```

      Chaining
      --------

      The return value of `then` is itself a promise.  This second, 'downstream'
      promise is resolved with the return value of the first promise's fulfillment
      or rejection handler, or rejected if the handler throws an exception.

      ```js
      findUser().then(function (user) {
        return user.name;
      }, function (reason) {
        return 'default name';
      }).then(function (userName) {
        // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
        // will be `'default name'`
      });

      findUser().then(function (user) {
        throw new Error('Found user, but still unhappy');
      }, function (reason) {
        throw new Error('`findUser` rejected and we're unhappy');
      }).then(function (value) {
        // never reached
      }, function (reason) {
        // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
        // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
      });
      ```
      If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.

      ```js
      findUser().then(function (user) {
        throw new PedagogicalException('Upstream error');
      }).then(function (value) {
        // never reached
      }).then(function (value) {
        // never reached
      }, function (reason) {
        // The `PedgagocialException` is propagated all the way down to here
      });
      ```

      Assimilation
      ------------

      Sometimes the value you want to propagate to a downstream promise can only be
      retrieved asynchronously. This can be achieved by returning a promise in the
      fulfillment or rejection handler. The downstream promise will then be pending
      until the returned promise is settled. This is called *assimilation*.

      ```js
      findUser().then(function (user) {
        return findCommentsByAuthor(user);
      }).then(function (comments) {
        // The user's comments are now available
      });
      ```

      If the assimliated promise rejects, then the downstream promise will also reject.

      ```js
      findUser().then(function (user) {
        return findCommentsByAuthor(user);
      }).then(function (comments) {
        // If `findCommentsByAuthor` fulfills, we'll have the value here
      }, function (reason) {
        // If `findCommentsByAuthor` rejects, we'll have the reason here
      });
      ```

      is fulfilled with an array of fulfillment values for the passed promises, or
      rejected with the reason of the first passed promise to be rejected. It casts all
      elements of the passed iterable to promises as it runs this algorithm.

      Example:

      ```javascript
      var promise1 = RSVP.resolve(1);
      var promise2 = RSVP.resolve(2);
      var promise3 = RSVP.resolve(3);
      var promises = [ promise1, promise2, promise3 ];

      If any of the `promises` given to `RSVP.all` are rejected, the first promise

        // result === 'promise 2' because it was resolved before promise1
        // was resolved.
      });
      ```

      `RSVP.Promise.race` is deterministic in that only the state of the first
      settled promise matters. For example, even if other promises given to the
      `promises` array argument are resolved, but the first settled promise has
      become rejected before the other promises became fulfilled, the returned
      promise will become rejected:

      ```javascript
      var promise1 = new RSVP.Promise(function(resolve, reject){
        setTimeout(function(){
          resolve('promise 1');
        }, 200);

      var promise2 = new RSVP.Promise(function(resolve, reject){
        setTimeout(function(){
          reject(new Error('promise 2'));
        }, 100);
      });

      RSVP.Promise.race([promise1, promise2]).then(function(result){
        // Code here never runs

      outside of the promise, so it bubbles up to your console if in the browser,
      or domain/cause uncaught exception in Node. `rethrow` will also throw the
      error again so the error can be handled by the promise per the spec.

      and you can watch for it in your console. You can also handle it using a
      rejection handler given to `.then` or `.catch` on the returned promise.
