  \brief     Physics policy for the Euler equation governing multi-material flow
    using a finite volume method
  \details   This file defines a Physics policy class for the compressible
    flow equations class dg::MultiMat, defined in PDE/MultiMat/DGMultiMat.h.
    This specific algorithm assumes multi-material flow with a single velocity
    (velocity equilibirum) and uses a finite volume discretization scheme. See
    PDE/MultiMat/Physics/DG.h for general requirements on Physics policy classes
    for dg::MultiMat.
