Bugfixes. Quick inspection suggests that expand_compounds works, but extensive tests are needed!

description:
Added compound_classes list and implemented expand_compounds (in only 6 lines).

There is a bug i don't quite understand though,
and I'm doing some quite fancy python stuff now...

description:
Added lists of terminal and nonterminal classes in classes.py.
Using these in transformations.py to handle some things more generally.
Added ufl_copy_handlers and ufl_reuse_handlers instead of ufl_handlers,
allowing reuse of unchanged subtrees in transformation algorithms.

Fixed ufl-analyse script to allow
 ufl-analyse *.ufl
which simplifies running it on all files under demo/ for testing.
