/* ==========================================================================
	Class :			CUMLLabelPropertyDialog

	Author :		Johan Rosengren, Abstrakt Mekanik AB

	Date :			2004-04-29

	Purpose :		"CUMLLabelPropertyDialog" is a dialog box wrapper derived 
					from "CDiagramPropertyDlg", used by "CUMLEntity"-
					derived objects to edit the object title attribute.

	Description :	Class-Wizard created class.

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

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