	CDiagramButton

	Author :		Johan Rosengren, Abstrakt Mekanik AB

	Date :			2004-03-31

	Purpose :		Encapsulates a "command button" as a CDiagramEntity 
					object.

	Description :	An example of a CDiagramEntity-derived class. Includes 
					an example of the Export function.

					The class uses a static class with GDI-helpers, 
					CStdGrfx, for drawing.

	Usage :
