Class
    Foam::cellZone

Description
    A subset of mesh cells.

    Currently set up as an indirect list but will be extended to use a
    primitive mesh.  For quick check whether a cell belongs to the zone use
    the lookup mechanism in cellZoneMesh, where all the zoned cells are
    registered with their zone number.
