Hi!

I've tested the new operators, and they seem to work without
problems. I have a feature request though :). It would be nice if I
could write this:

mult(mu, e)

like this:

mu * e

where "mu" is a Constant (scalar) and "e" is an array (epsilon(u) in
this case). I have no problems requiring functions for esoteric
products, but scalar-vector or scalar-scalar multiplication should
just be "*" in my opinion, since it's used so often.

It's not very critical though, but I think it should just be adding a
case for an array for multiplication to the FFC algebra.
