	Purpose
		The tab control is used by the Ultimate Grid
		to provide ability to switch between grid
		sheets.  A notification is called everytime
		any tab is clicked on, this notification
		identifies which tab user clicked on and
		provides a convienient location to react
		to user's action.

		This control is located just left to the 
		horizontal scroll bar, where its size is
		dictated by the width of the scroll bar
		and grid's window.
