Yes, but I'll fix evaluate_basis and get correct results for quadrature code first.

Yes, we should manually check for family == "Quadrature" then return a FFC.QuadratureElement and make sure it has the same member functions as the FIAT.FiniteElement that we currently expects around the code.

I assume Anders knows what to do. :)

I'm looking into this now. It is related to how intelligent remove_unused is.
I think the easiest solution is to create a set of used variables when generating the code and the have remove_unused operate on the jacobian snippets, which will be the fastest way of doing things anyway.
A fix will be on it's way tomorrow.

I'll take a look, should be a format thing from changing from Jinv_ -> K

I don't know what to make of this, but I'll take a look once the other issues has been sorted out.

When running the regression tests, I guess that if the generated code is equal to the reference code there is no need to proceed compiling and running the test program. This will save us some time when running the test suite.
