this is basically identical to createAnonymousTBAARoot in MDBuilder.h, though a
little less efficient.  How about moving the createAnonymousTBAARoot code to
getSelfReferencing, fix up users, and remove createAnonymousTBAARoot.  Also, I
think the name getAnonymous would be better than getSelfReferencing.

Ciao, Duncan.
