    Listen for finished event, should be able to pull out goal states, somehow.

    Level has a list of thangs. You must find which one of the thangs has programmable components.
    The programmable thangs you would create the aether instance for each one for each of its programmable
    methods. Like tome_view.coffee/createSpells is doing. The world will reconstruct the clones, so if it is
    a cloneOf, just skip it. Any programmable method where the method is actually like something that has a name
    and a source, you must create an aether out of it. spellkeys must be created, so once you have that
    you can find matching spellkeys and go get the code.
    To make an aether instance, look at spell.coffee

    protectAPI: false
    includeFlow: false

    Look in level.thangs and world.coffee
    loadFromLevel is slow but works
    Find every thang which has a component which has an original of the ID of the original programmable component
    The config property will have original, then config.
