[Kristian Oelgaard <k.b.oelgaard@xxxxxxxxxx>]

Quoting FFC <ffc@xxxxxxxxxx>:

It is now possible to define an element on an interval

element = FiniteElement("Lagrange", "interval", 1)

Only tested (not thoroughly) for Lagrange type elements

The following is working:
v = TestFunction(element)
u = TrialFunction(element)
f = Function(element)
a = dot(grad(v), grad(u))*dx
L = v*f*dx

The following is NOT working:
 - exterior/interior integrals
 - evaluate_basis()
 - evaluate_basis_derivatives()
