Detailed Description

This is the container class for all sprites. It handles AI calling, Moving, Collision detection and drawing. The engine position is a camera position, everything is drawn with these values as an offset. Sprites beyond the screen boundaries will not be drawn, but will have their AI code called, moved etc.
