 * @class   vtkSMGlobalPropertiesLinkUndoElement
 *
 * This UndoElement is used to link or unlink GlobalPropertyManager property
 * to a property of an arbitrary Proxy.
 * This class is automatically build inside the vtkSMProxyManager when
 * GlobalPropertyLinks are changed.
 * FIXME: This class is currrently non-functional. I need to re-energize this
 * class. It's falling down the priority chain for now.
