	---Purpose: Constructs point datums to be used in construction of
    	-- composite shapes. The datum is displayed as the plus marker +.

    	---Purpose: Allows you to remove color settings.

    	---Purpose: Allows you to provide settings for a marker. These include
    	-- -   type of marker,
    	-- -   marker color,
    	-- -   scale factor.    
    
    UnsetMarker(me:mutable);
    	---Purpose: Removes the marker settings.
