* GRHydro: write floating point operations in left/right symmetric mannerrhaas2013-07-06
| | | | | | | | | | | | | | | | * write DIFF_X_4 in an explicitly symmetric manner this ensures that the order of evaluation is such that symmetry in i+/-1 is preserved by the numerical derivative * add code to make ePPM and Source more symmetric this is an attempt to better preserve the CoM in long runs by eliminating asymmetries between left and right. This is fragile in that it does not make the code more robust against existing roundoff-level asymmetries, it only prevents them from developping.

* GRHydro: add option to switch to oPPM on a given refinement levelrhaas2013-07-06
| | | | | | | | | | | | When reconstruction method is enhanced PPM, this change allows using old PPM on one refinement level, whereas the rest of the reflevels will use enhanced PPM. It is only for hydro, but could be extended to MHD also.

This patch is necessary for NS collapse when ePPM+Refluxing is used. The idea is due to Roland.

| | | | | | | | | | | | Support using precisions other than real*8 in GRHydro by removing all explicit references to double precision functions and constants, and using type-generic functions and constants instead. In particular, use "one" and "half" as constants in some places, and use "abs", "max" etc. instead of "dabs", "dmax" etc. git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinEvolve/GRHydro/trunk@319 c83d129a-5a75-4d5a-9c4d-ed3a5855bf45
