ufc::cell not properly exposed in Python interface

[Prof Garth Wells]

ufc::cell attributes are not properly exposed in Python. From test/unit/python/function, reproduce with py.test -k test_doc_string_python_expressions test_expression.py

It does work if some of the preceding tests are called first.

Expose ufc::cell members in Python interface (fixes Issue #656)
