Class
    Foam::zoneGenerators::invert
 
Description
    A zoneGenerator which initially selects all the elements in the zones and
    then removes the elements from the given list of zoneGenerators
 
    This is equivalent to using the zoneGenerator::difference with
    \c all as the first zoneGenerator in the list.
 
Usage
    \table
        Property     | Description             | Required | Default value
        type         | Type: invert            | yes      |
        name         | Name of the zone        | no       | zoneGenerator name
        zoneType     | Type of zone            | no       | all the zone types
        moveUpdate   | Switch to update after mesh motion | no | false
    \endtable
    These options are followed by a list of any number of zoneGenerators which
    can either generate the zones locally or return zones from the lists of
    zones held by the mesh using the zoneGenerators::lookup zoneGenerator.
 
    Each zoneGenerator returns a zoneSet containing a pointZone and/or a
    cellZone and/or a faceZone, the zoneGenerators::invert operation
    combines each of the zone types unless the \c zoneType is specified in which
    case only the zones of that type are combined.
 
    A cellZone named \c notConeOrAnnulus containing all the cells mesh except
    those with centres inside the predefined \c cone1 cellZone which is
    looked-up from the cellZoneList or the locally defined annulus is be
    generated by
    \verbatim
        notConeOrAnnulus
        {
            type        invert;
 
            cone1
            {
                zoneType        cell;
            }
 
            annulus1
            {
                type        annulus;
                zoneType    cell;
 
                point1      (-0.0075 0 -1);
                point2      (-0.003 0.0025 1);
                outerRadius 0.002;
                innerRadius 0.001;
            }
        }
    \endverbatim
