>   class ChangeLineWidthOpDesc : public OpDescriptor

    Author:     Simon_Maneggio (Xara Group Ltd) <camelotdev@xara.com>
    Created:    03/06/94

    Purpose:    OpDescriptor to allow the user to change the line width of all selected
                objects, or to set the AttributeManager's Current line width attribute if 
                no objects are selected.

                The OpDescriptor Invokes the OpApplyAttribToSelected operation if nodes
                are selected.
