-// NOTE: next questions:
-// * what is the lifecycle of the getStudios etc. requests? Are they guaranteed to be there
-//   on page load? Are they ever updated, e.g. after you join one?
-
-// design decisions:
-// * we should treat "waiting" to mean, user has requested the modal to be closed;
-//   that is, if you click ok and it's waiting for responses, then you click x,
-//   it closes and sets waiting to false?
-//   then in the checkForOutstandingUpdates function, we close the window
-//   iff waiting is true.
-//   that avoids the situation where you close the window while a request is
-//   outstanding, then reopen it only to have it instantly close on you.
-// * keep the okay button, it sets up an overall spinner until everything is resolved
-// * but you can totally close the window regardless
-
-// sample data:
-// this.studios = [{name: 'Funny games', id: 1}, {name: 'Silly ideas', id: 2}];
-// studios data is like:
-// [{
-//   id: 1702295,
-//   description: "...",
-//   history: {created: "2015-11-15T00:24:35.000Z",
