grad_grad  Laplacian operator
SYNOPSIS
form(const space V, const space& V, "grad_grad");
DESCRIPTION
Assembly the form associated to the Laplacian operator on a finite element space V:
/

a(u,v) =  grad(u).grad(v) dx

/ Omega
The V space may be a either P1 , P2 or P1d finite element space. See also form(3) and
space(3).
EXAMPLE
The following piece of code build the Laplacian form associated to the P1 approximation:
geo g("square");
space V(g, "P1");
form a(V, V, "grad_grad");
