Class
    Foam::zoneGenerators::externalPoints

Description
    A zoneGenerator which selects the static external points

    i.e. points that are outside interior of the cylinder liner

Usage
    \table
        Property     | Description              | Required | Default value
        type         | Type: externalPoints     | yes      |
        name         | Name of the zone         | no       | zoneGenerator name
        moveUpdate   | Switch to update after mesh motion | no | false
    \endtable

    To create the \c externalPoints pointZone:
    \verbatim
        externalPoints;
    \endverbatim
    or the same pointZone but named \c staticPoints:
    \verbatim
        staticPoints
        {
            type        externalPoints;
        }
    \endverbatim
