    """This will return the SEName to be used as intermediate hop
    for a multiHop transfer.
    To find the matching rule, we look in this order:
        * For the specific SE Name
        * For its base SE name
        * For a rule named "Default"
    We do apply this order to the couple ``(source, destination)``, starting with
    ``destination`` (see ``priorityList``) until we find a match.
    The best way not to have a multihop is to not define a route, however
    there are cases when you may want to factorize your configuration,
    and thus want to disable a config. For example, you can define a multihop
    for a specific source to a base SE destination, but do not want multihop
    for a specific child of this base SE. Use the value ``disabled`` for that.
    A lot more examples and illustrations are available in the test module ``Test_DefaultFTS3Plugin``.
