Dear sir

i am not able to multiply test function from nedelec space and known function of 3 dimensional.

```
import dolfin
from dolfin import*
import matplotlib.pyplot as plt
mesh = UnitCubeMesh(10, 10, 10)
V=FunctionSpace(mesh, "Nedelec 1st kind H(curl)", 1)
u=TrialFunction(V)
v=TestFunction(V)
f=Expression(("x[0]", "x[1]", "x[2]"), degree=1)
a=f*v*dx
```
