Class
    Foam::pointZone

Description
    A subset of mesh points.
    The labels of points in the zone can be obtained from the addressing()
    list.

    For quick check whether a point belongs to the zone use the lookup
    mechanism in pointZoneMesh, where all the zoned points are registered
    with their zone number.
