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.
