split() not working for parts extracted from multimesh functions in Python

[Anders Logg (Chalmers)]

If w is a mixed MultiMeshFunction, then the following does not work:

w.part(i).split()

This is bacause w.part(i) returns an object that is only a dolfin::Function.

[Jan Blechta]

You should be able to use the constructor Function(g) for isinstance(g, cpp.Function) in MultiMeshFunction.part() method - in fact in every method returning Function.
