Output is:
- volScalarField with regions as different scalars (-detectOnly) or
- mesh with multiple regions or
- volScalarField with regions as different scalars (-detectOnly)
or
- mesh with multiple regions and directMapped patches. These patches
either cover the whole interface between two region (default) or
only part according to faceZones (-useFaceZones)
or
- mesh with cells put into cellZones (-makeCellZones)
