The functional changes needed in Top should just be refactored as extensions to
the existing Top so that they can coexist in the Ptolemy tree.  This eliminates
the need for someone to maintain the class against changes in the Ptolemy tree.
  We have 5 years of evidence that people do not maintain the differences even
for classes that change infrequently.  We've inserted extension hooks in
ptolemy before -- its just not that hard to find a way to do these things that
is maintainable without overrides but still provides the needed functionality.
