Gets a ``ObjectiveBankList`` corresponding to the given ``IdList``.

        In plenary mode, the returned list contains all of the objective
        banks specified in the ``Id`` list, in the order of the list,
        including duplicates, or an error results if an ``Id`` in the
        supplied list is not found or inaccessible. Otherwise,
        inaccessible ``ObjectiveBank`` objects may be omitted from the
        list and may present the elements in any order including
        returning a unique set.

        arg:    objective_bank_ids (osid.id.IdList): the list of ``Ids``
                to retrieve
        return: (osid.learning.ObjectiveBankList) - the returned
                ``ObjectiveBank`` list
        raise:  NotFound - an ``Id was`` not found
        raise:  NullArgument - ``objective_bank_ids`` is ``null``
        raise:  OperationFailed - unable to complete request
        raise:  PermissionDenied - authorization failure
