    A Zone is a mapping from names to nodes.  The zone object may be
    treated like a Python dictionary, e.g. zone[name] will retrieve
    the node associated with that name.  The I{name} may be a
    dns.name.Name object, or it may be a string.  In the either case,
    if the name is relative it is treated as relative to the origin of
    the zone.

    @ivar rdclass: The zone's rdata class; the default is class IN.
    @type rdclass: int
    @ivar origin: The origin of the zone.
    @type origin: dns.name.Name object
    @ivar nodes: A dictionary mapping the names of nodes in the zone to the
    nodes themselves.
