- simplify procAddressing read/write - avoid accessing points in faMeshReconstructor. Can rely on the patch meshPoints (labelList), which does not need access to a pointField - report number of points on decomposed mesh. Can be useful additional information. Additional statistics for finite area decomposition - provide bundled reconstructAllFields for various reconstructors - remove reconstructPar checks for very old face addressing (from foam2.0 - ie, older than OpenFOAM itself) - bundle all reading into fieldsDistributor tools, where it can be reused by various utilities as required. - combine decomposition fields as respective fieldsCache which eliminates most of the clutter from decomposePar and similfies reuse in the future. STYLE: remove old wordHashSet selection (deprecated in 2018) BUG: incorrect face flip handling for faMeshReconstructor - a latent bug which is not yet triggered since the faMesh faces are currently only definable on boundary faces (which never flip)
