UMLEditor - revisiting the vector editor

/* ==========================================================================
	Class :			CUMLLinkPropertyDialog

	Author :		Johan Rosengren, Abstrakt Mekanik AB

	Date :			2004-06-21

	Purpose :		"CUMLLinkPropertyDialog" derives from "CDiagramPropertyDlg".
					It is a wrapper for the link property dialog.

	Description :	A standard Class-Wizard created dialog box class.

	Usage :			In the "CUMLEntity"-derived class, add a member of 
					the "CUMLInterfacePropertyDialog"-derived class, and call 
					"SetPropertyDialog" in the constructor.

					The dialog is displayed as a modeless dialog. The 
					editor will hide the dialog automatically when another
					object is selected, no special Close-button is 
					necessary.

					The dialog template with the resource id 
					"IDD_UML_DIALOG_PROPERTY_LINK" 
					must be added to the project.

   ========================================================================
	Changes :
		8/7 2004	Support for the Interface line type added.
