Unit tests and bugfixes for evaluation, for example:

        cell = triangle
        x = cell.x
        I = Identity(cell.d)
        s = (x[i]*x[j])*I[i,j]
        e = s((5,7))
        #v = sum_i sum_j x_i x_j delta_ij = x_0 x_0 + x_1 x_1
        v = 5**2 + 7**2
        self.assertTrue(e == v)

description:
Split Integral into Integral and Measure,
inspired by the wording in the manual
"dx is a measure for integration".
Metadata for integration options is
associated with the Measure, and an
Integral has an Expr (integrand) and a Measure.

Fixed Form such that integrals with
measures differing only by metadata
are not combined.
