I have thought about this problem quite a while, and I have not found
a way to implement a default hierarchic iterator for faces using only
topological information. You can't use vertex numbers because they
are not the same across different levels. I ended up using normal
tests for a while, but that only works for boundary faces and only
if that boundary is not parametrized. Now I start to reuse parametrized
boundaries again, and in my desperation I now built my very
special UGGrid interface extension to solve my problem. Works-for-me(tm)
but a HierarchicIterator would be much nicer.
