	Class :			CUMLEntityClass

	Author :		Johan Rosengren, Abstrakt Mekanik AB

	Date :			2004-04-29

	Purpose :		"CUMLEntityClass", derived from "CUMLEntity", 
					represents an UML class box. 	

	Description :	The class implements the necessary functions for 
					cloning and creation from text ("Clone" and 
					"CreateFromString"). It draws a rectangle using the 
					title attribute of "CDiagramEntity" as the text 
					contents. The box can link from all four sides.
					The class contains separate arrays for the properties, 
					operations and attributes of this class ("CPropertyContainer", 
					"COperationContainer" and "CAttributeContainer" 
					respectively).

	Usage :			When loading, create with "CUMLControlFactory::CreateFromString". 
					Otherwise, create instances in the application view or dialog and 
					add them to the editor with "StartDrawingObject". The 
					editor takes responsibility for the object.
   ========================================================================
	Changes:		8/7 2004	Changed base class handling in c++-export 
								from "CString" to "CStringArray" to support 
								multiple inheritance
					9/7 2004	Setting baseclass(es) to baseClass property 
								when importing class from h-file.
					12/7 2004	Checking for void return type (n0mer)

	Usage :			The function should clean up all selected
