17 * \ingroup DuffyTrick
18 * \brief quadrature routine for common vertex case.
19 * \todo be sure that map2element computes the weight h*Q.w(i) such that the
20 *integrand may then be scaled by qp1.weight * qp2.weight here we just set one
21 *weight to the actual weight, while the other one will be set to 1. This is to
22 *remain conforming to the structure of integrate0/1.
23 *
24 * Information that map2element has to provide:
25 * xi; w; Chi(xi); dChidx(xi); dChidy(xi);
