Subject: Make ModelGraphTraverser assume that all traversed objects provide
 ILocation.  Make WrappingModelGraphTraverser assume that *no* traversed
 objects provide ILocation.  This makes it unnecessary to explain why the root
 object in a WrappingModelGraphTraverser setup needs to supply the ILocation
 interface.  Now it doesn't.
