Low Diffusion Efficient Upwind Scheme

Zha suggests a modification to an E-CUSP scheme for compressible flow governing equations by replacing the pressure term with total enthalpy in the dissipation term of the energy equation. This removes the temperature oscillation, thus achieving low numerical dissipation.
