Detailed Description

Integrator for the DG form: alpha < rho_u (u.n) {v},[w] > + beta < rho_u |u.n| [v],[w] >, where v and w are the trial and test variables, respectively, and rho/u are given scalar/vector coefficients. The vector coefficient, u, is assumed to be continuous across the faces and when given the scalar coefficient, rho, is assumed to be discontinuous. The integrator uses the upwind value of rho, rho_u, which is value from the side into which the vector coefficient, u, points.
