Detailed Description
Computes 1D fluxes using a Riemann solver similar, but not identical, to Toro's FORCE (First-ORder-CEntred) flux.
PURPOSE: Computes 1D fluxes using a Riemann solver similar, but not identical, to Toro's FORCE (First-ORder-CEntred) flux. It uses the average of a Lax-Wendroff and HLLE flux for sub-sonic flow, and the appropriate upwind flux otherwise.
