	Purpose
		This class is used internally by the grid
		to keep track of which cells need redrawing
		The grid draws its cells in an extremely
		optimized manner which gives it is great
		speed.

		This is the class which helps the optimization
		process by maintaining a list of cells that
		need to be redrawn.

		When the grid is doing the drawing it calls
		IsInvalid function to see if a cell needs
		to be redrawn.
