//	Desc	: Expose external functions of the 2D game Framework
//		Actor Manager. This manager controls the actors. An actor
//		is simply a 2D sprite. Functions include rotation, collision detection,
//		and linking to animations for costumes and x,y positions. Actors can
//		be set either on or off stage and a lifespan allows an actor to 
// 		automatically become offstage after a set timespan.
