Uhm, I just realized there's a conceptual bug here.
The only TopoGeometry objects that would be affected by a change in
another TopoGeometry object are those used by hierarchical layers.

TopoGeometry objects are only defined by relations, if you _change_
a TopoGeometry you basically change its set of relations, which 
doesn't affect other sets.
