NAME
       grad -- gradient operator

SYNOPSIS
	     form(const space V, const space& M, "grad");

DESCRIPTION
       Assembly the form associated to the gradient operator on a finite element space V:

		       /
		       |
	     b(u, q) = | grad(u).q dx
		       |
		       / Omega

       The  V  space  may  be  a  either P1  or P2  finite element space, while the M space may be P0  or P1d  respectively.  See also form(2) and
       space(2).

EXAMPLE
       The following piece of code build the divergence form associated to the P1 approximation:

	       geo omega("square");
	       space V(omega, "P1");
	       space M(omega, "P0", "vector");
	       form b(V, M, "grad");
