topoSet: cellZoneSet, pointZoneSet extensions

cellZones and pointZones can now be created in one action without the
need to first create a cellSet or pointSet and converting that to the
corresponding zone, e.g.

actions
(
    // Example: create cellZone from a box region
    {
        name    c0;
        type    cellZoneSet;
        action  new;
        source  boxToCell;
        sourceInfo
        {
            box   (0.04 0 0)(0.06 100 100);
        }
    }
);
