Hi!

I've verified that the assembly is correct for the Elasticity form in
DOLFIN (compared against a reference) and I'm using the
signature-enabled FFC when working on the updated elasticity module,
and the output seems fine (just eyeball verification). So the
signature factorization seems to be working fine, great job. I haven't
gotten to the operators yet.
