I think it's great. I've fixed a couple of bugs (still no tests),
and added some minor features.

The issue left to resolve is value_rank() and value_dimension(i) for
MixedElement instances that are not VectorElement or TensorElement
instances. I think we should use the same convention as we use for
ufc::finite_element::value_*, which are essentially the same
functions. The MixedElement.value_rank implemented today (value_rank
== len(subelements)) doesn't make sense, e.g. Taylor-Hood is not a
second order tensor valued element.
