	Purpose
		The CUGGrid takes care of the main grid area,
		this is where all of the cells are drawn and
		most user interaction takes place.
	Details
		- This class handles drawing of all cells,
		  excluding cells on headings.
		- All of the mouse and keyboard events
		  are routed to the CUGCtrl derived class
		  in form of virtual functions (notifications).
