ENH: simple faMeshSubset (zero-sized meshes only) ENH: additional access methods for faMesh, primitive geometry mode - wrapped walking of boundary edgeLabels as list of list (similar to edgeFaces). - primitive finiteArea geometry mode with reduced communication: primarily interesting for decomposition/redistribution (#2436) ENH: extra vtk debug outputs for checkFaMesh - report per-processor sizes in the mesh summary
