The GamePlayViewConroller is a view controller for SPView. It is a subclass of UIViewController so it can be used on a navigation stack or as a model view controller.

GamePlayViewController responds to the application moving to/from the background, and listens for a “StopGame” NSNotification.

It also has SPStage property. Set this property with your stage before presenting the view controller.
