EditStructuralUnit - create and/or alter parent, ranking or state
    information for a Structural Unit.

    The EditStructuralUnit LUMP API script allows Structural Units to be
    created, have parents added/removed, be reranked alongside other
    siblings and have the editing state changed.

    *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
    *operation* - What operation is requested. Valid operations are
    "create", "addparent", "removeparent", "rerank", "delete", "undelete"
    and "changestate". Defaults to "create" if not specified.
    *suid* - ID for the Structural Unit.
    *sutid* - ID for the Structural Unit Type.
    *parent_su_id* - ID for the Structural Unit that is the parent for the
    Structural Unit being created/edited.
    *rank* - ranking position for this Structural Unit.
    *state* - Editing state for this Structural Unit. Valid states are
    "draft", "published" and "suppressed" (the latter being effectively
    "deleted" but it doesn't actually remove the Structural Unit from the
    database immediately).

    When a Structural Unit is created, a Structural Unit Link table is also
    created to attach it to the specified parent Structural Unit. At the
    same time, the parent's ACLs are copied to the new Structural Unit so
    that initially the same people can access it. A successful creation will
    return the ID of the new Structural Unit in a <structural_unit_id>
    element inside the <returns> section of the LUMP XML response, along
    with an <error_code> indicating "SUCCESS". Other operations don't return
    anything in the <returns> section of the XML response, relying soley on
    the <error_code> to convey success or failure.
