I've attached a handful of headers (not that I am paranoid about my cpp files, they're just super boring and obvious :) ).

SubApp = a game state (terrible name)
Widgets = the few Widgets Terava uses
WidgetApp = a state that has a widget root, or two in splitscreen
LevelCompletedApp = an app that is shown in splitscreen
Transformer = how I handle different devices and stuff.
