GODMARK: something wrong with comparing multiple velocities since grid/metric changes in space (i.e.

v=dx/dt means something different at each grid point) GODMARK: assumes boundary zones exist (flux method of bounding won't work) – have to apply extra limits on values (i,j,k) used here

defines an effective maximum wave speed centered on the cell interface (FACE)

might choose wavespeeds that correspond to interpolation stencil, which to first approximation is a symmetric stencil of size interporder[reallim]
