IntegrateBC function from ex27p.cpp. For boundary verification. Compute the average value of alpha*n.Grad(sol) + beta*sol over the boundary attributes marked in bdr_marker. Also computes the L2 norm of alpha*n.Grad(sol) + beta*sol - gamma over the same boundary.

This function effectively implements equation 19 of the paper (see header). \Phi [y(x)]
