----------------

Updates for new version of FFC, including work on functions (coefficients).
The remaining showstopper is getting FFC to correctly count and number
the coefficients of a form.

For testing, see the Poisson module. To get functions working, Form needs
to be initialized with the correct number of functions and each function
needs to be added (in the correct order) using Form::add(). This will
create a coupling between functions and coefficients.
