RankSUs - re-rank a collection of structural units

    The RankSUs CGI script allows the ranking for a set of LUMP Structural
    Units to be managed.

    *username* - Name of user running this CGI script. Required unless web
    server authentication is in use (when it is, the web server
    authenticated user is used instead).
    *password* - Password for the user. This is only required if the web
    server is not handling the user authentication and if no security hash
    parameter is being given.
    *security_hash* - An opaque value used to authenticate the user without
    requiring the password to be sent. This value is generated by a previous
    execution of a LUMP API script and may well be time limited. It is only
    required if no password or webserver authentication is done.
    *act_as* - Users in the SysAdmins group can elect to act on the behalf
    of other users once they are themselves authenticated. If this parameter
    is present it should contain the username of the user that should be
    switched to if this option is available and the real user has been
    authenticated successfully. Optional.
    *session_id* - An opaque string as far as the server is concerned that
    is intended solely to allow async clients to differentiate different
    results more easily. Optional.

  Specific for this script
    *parent_su_id* - the structural unit ID of the parent SU under which all
    this ranking is taking place. For example it might be a reading list SU
    ID, and ranking will be for books, journals, etc underneath it. This is
    a required parameter.
    *suid_rank_pairs* - a comma separated list of structural unit ID and
    rank number pairs, with the SU IDs and ranks separated themselves using
    colons. Eg: 1435:10,3456:20,45642:30. This is a required parameter.

    The <returns> section of the XML result is empty and the <error_code> is
    used to indicate success or failure of the operation.
