Will look just as it does today, with "::" --> "" on the DOLFIN side.

With the following form in FFC (in say Poisson.form),

   f = Function()
   L = v*f*dx

you will be able to do

   Function f;
   PoissonLinearForm L(f);

in DOLFIN. Same as before, but PoissonLinearForm instead of Poisson::LinearForm.

It remains to modify the Assembler interface to

  void assemble(GenericTensor& A, const ufc::form& form, Mesh& mesh,
                Array<Function*> coefficients);

and add a function

  void assemble(GenericTensor& A, const NewForm& form, Mesh& mesh);

that calls the first one. (The class NewForm has a member coefficients.)

It also remains for the assembler to take the array of coefficient
functions and interpolate the values into the double** w array that
goes into tabulate_tensor().

I should be able finish this next week, modulo some bugs.
