Class
    Foam::zoneGenerators::write

Description
    A zoneGenerator which writes all existing zones from the mesh

Usage
    \table
        Property     | Description             | Required | Default value
        type         | Type: write             | yes      |
        zoneType     | Type of zone            | no       | all the zone types
    \endtable

    Examples:
    To write all the zones that are changing:
    \verbatim
        writeAllZones
        {
            type        write;
        }
    \endverbatim
    or to write only the cellZones:
    \verbatim
        writeCellZones
        {
            type        write;
            zoneType    cell;
        }
    \endverbatim
    When called from the top-level of the createZonesDict or zonesGenerator
    files which is the most likely use the simpler syntax to write all the zones
    that are changing can be used:
    \verbatim
        write;
    \endverbatim
    or to write only the cellZones:
    \verbatim
        write
        {
            zoneType    cell;
        }
    \endverbatim
