    - in various situations with mesh regions it is also useful to
      filter out or remove the defaultRegion name (ie, "region0").
      Can now do that conveniently from the polyMesh itself or as a static
      function. Simply use this
          const word& regionDir = polyMesh::regionName(regionName);
      OR  mesh.regionName()
      instead of
          const word& regionDir =
               regionName != polyMesh::defaultRegion
             ? regionName
             : word::null
      Additionally, since the string '/' join operator filters out empty
      strings, the following will work correctly:
