FYI: Use markdown syntax for documentation
http://daringfireball.net/projects/markdown/syntax [eventName], and it doesn't
need to be in its own sentence. The documentation is intended to be more natural
like a comment.

[Emily Fortuna, 2013/01/23 19:28:04]

any reason why you're using the $ to start all of these classes? That's
something our JavaScript compiler does to its generated code, but I've not seen
us do it with our Dart code itself.

[sashab, 2013/01/23 22:24:53]

I need to distinguish, for example:
  chrome.app.window
from:
  AppWindow

chrome.app.window is the API's AppWindow, whereas AppWindow is an actual type.

I'm not sure on the best naming convention. Maybe APIAppWindow?
