I guess I'm just worrying about performance in python, since I would
have to do one method call for each vertex and one for each tet. I may
be prematurely optimising here, but IIRC even method calls to SWIG
wrapped C++ classes have a fair amount of overhead. Since I already
have the vertex coordinates and cell -> vertex connectivity data in
arrays, it is obviously much faster to just stuff them directly into
the dolfin structures?
