Detailed Description

BilinearFormIntegrator for Neumann boundaries using the shifted boundary method. A(u,w) = <[nabla u + nabla(nabla u).d + h.o.t.].nhat(n.nhat),w>-<grad u.n,w> where h.o.t are the high-order terms due to Taylor expansion for nabla u, nhat is the normal vector at the true boundary, n is the normal vector at the surrogate boundary. Since this interior face integrator is applied to the surrogate boundary (see marking.hpp for notes on how the surrogate faces are determined and elements are marked), this integrator adds contribution to only the element that is adjacent to that face (Trans.Elem1 or Trans.Elem2) and is part of the surrogate domain.
