This sounds reasonable to me, but one problem could be in the demos.
I have noticed that we need to use "unsigned int" in the demos rather
than "uint" even though "uint" is in namespace dolfin.

It feels natural to write "uint" or "unsigned int" in the demos, but
std::size_t does not feel intuitive. But it should be possible to make
thhe typedef to std::size_t and use "uint" in the demos and throughout
the code,
