 Zach Etienne found (last year on August already) that

 > In GRHydro_ReconstructPoly.F90, notice that after gzz in the
 SimplePPM_1d()
 > and SimplePPM_1dM() function calls, psi4 is passed. However, if you look
 at
 > the SimplePPM_1d() and SimplePPM_1dM() routines (within
 GRHydro_PPM.F90),
 > you will find that psi4 is not a variable in the function call list, and
 > beta^i should come after gzz, for flux_direction i.

 Pull request https://bitbucket.org/einsteintoolkit/einsteinevolve/pull-
 request/6/fix-usage-of-psi4-in-polytype/diff fixes this.
