 Description: Definition of CPersistMDIFrame class used to make MDI Main
			  frames persistent.
			  To use:
			  1. Derive a class from it instead of CMDIFrameWnd.
			  2. In the constructor call SetProfileHeading() to set the
			     registry key where to save the state. Its default value
				 is "Main Frame".
			  3. In the constructor call SetManageBarStates to set whether
			     bar states should be persistent too. Its default value is false.
