Hello!

We have been discussing to inherit the ffc.{Test,Trial,Basis}Function in 
dolfin, and instantiate the function with a functionspace instead of an 
element. Then in assemble.py we extract the functionspaces from the 
basisfunctions in Formdata (Anders promised this). 

I had a look in Formdata to try to just extract the basis functions, similare 
to the coefficients. But the problem is that these functions are not 
represented in the monomial as the original u and v as they were created by 
the user. 

I suppose this is a "feature" of the algrebra in ffc or have I missunderstood 
it? The function that is used to define the coefficients can be extracted 
using with c.f, should this be added for the basisfunctions too? 

Will this be an issue in ufl?
