/*!

  This class is used to register callbacks to track the deletion of UI
  objects.

  The first parameter passed to the add callback method is the name of
  the UI that will trigger the callback.

  The method returns an id which is used to remove the callback.

  To remove a callback use MMessage::removeCallback.

  All callbacks that are registered by a plug-in must be removed by
  that plug-in when it is unloaded.  Failure to do so will result in a
  fatal error.
