	Purpose
		The CUGCheckBoxType class is standard check box cell type in the
		Ultimate Grid control.

		By default an instance of this class is created and added, and
		can be used without any additional coding.

		To use this cell type all you have to do is set any cell's cell type
		property to UGCT_CHECKBOX (or 2).

		Extended styles
			UGCT_CHECKBOXUSEALIGN	- use this style to allow the check box
									  to respect the alignment set to a cell.
									  Please note that when this style is set
									  then the check box will not draw the text
									  assigned to a cell.

			UGCT_CHECKBOXFLAT		- check box is drawn in default flat mode
			UGCT_CHECKBOX3DRECESS	- the frame of the check should be shown as sunken
			UGCT_CHECKBOX3DRAISED	- the frame of the check should be shown as raised

			UGCT_CHECKBOXCROSS		- when a check box is set than the check
									  mark will be drawn as a cross.
			UGCT_CHECKBOXCHECKMARK	- when a check box is set than the check
									  mark will be drawn as a check mark.

			UGCT_CHECKBOX3STATE		- the check box is using 3 check states.
										- not checked
										- checked
										- un certain

		Notificatoins sent to the OnCellTypeNotify:
			UGCT_CHECKBOXSET		- provides information that the user has 
									  changed the state of the check box
