Otherwise, it only applies to the object on which it was given.
Types can keep pointers to all instances or tokens of themselves.
This will prevent tokens of this object from being made. If default is not to create instances, then create one anyway for this object. Only the type name will be registered. Since the save files are text, they can be large, so it is a good idea to auto-compress dump files for large objects. This indicates that there is a group object as a member of this one who's objects should appear in menus where this object appears.
