Looks good, but this might not be needed with the UFC-based assembly.

The current BilinearForm interface for evaluation of the element
tensor looks like this:

    void eval(real block[],
              const AffineMap& map,
              real det) const;

but the corresponding UFC interface looks like this:

    void tabulate_tensor(double* A,
                         const double * const * w,
                         const ufc::cell& c) const;

A is the same as block.

w is a list of expansion coefficients for the functions in the form,
and corresponds to the member data c in BilinearForm.

The AffineMap and determinant are no longer arguments to the
tabulate_tensor (eval) function, since they may not be needed, so the
generated code will need to compute the affine map and the determinant
when they are needed.

Perhaps the AffineMap will be needed for other things, but it won't be
needed for the generated code.
