Gets the ``Bank`` specified by its ``Id``.

        In plenary mode, the exact ``Id`` is found or a ``NotFound``
        results. Otherwise, the returned ``Bank`` may have a different
        ``Id`` than requested, such as the case where a duplicate ``Id``
        was assigned to a ``Bank`` and retained for compatibility.

        arg:    bank_id (osid.id.Id): ``Id`` of the ``Bank``
        return: (osid.assessment.Bank) - the bank
        raise:  NotFound - ``bank_id`` not found
        raise:  NullArgument - ``bank_id`` is ``null``
        raise:  OperationFailed - unable to complete request
        raise:  PermissionDenied - authorization failure occurred
