/**
 * @class vtkCGNSSubsetInclusionLattice
 * @brief extends vtkSubsetInclusionLattice to CGNS friendly API.
 *
 * vtkCGNSSubsetInclusionLattice simply makes it easier for users (and the
 * vtkCGNSReader) to query vtkSubsetInclusionLattice using CGNS terminology.
 *
 * @par Zone names and partitioned files
 *
 * vtkCGNSFileSeriesReader supports reading of a partitioned file series where
 * each file has all timesteps but only the data from the rank the file was
 * written out on. In those cases, some sims use suffixes for zone names to
 * identify proc number e.g. `blk-1_proc-0`, `blk-1_proc-1`, etc. Since this has
 * a tendency to make the SIL unwieldy, we sanitize zonenames by default to
 * remove the `_proc-.*` suffix. All API on vtkCGNSFileSeriesReader that takes a
 * zonename sanitizes it. If you use API on vtkSubsetInclusionLattice you may
 * need to sanitize zonenames manually by calling `SanitizeZoneName`.
 *
