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

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

        arg:    gradebook_column_id (osid.id.Id): ``Id`` of the
                ``GradebookColumn``
        return: (osid.grading.GradebookColumn) - the gradebook column
        raise:  NotFound - ``gradebook_column_id`` not found
        raise:  NullArgument - ``gradebook_column_id`` is ``null``
        raise:  OperationFailed - unable to complete request
        raise:  PermissionDenied - authorization failure
