NAME
       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(2) and space(2).

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");
