Gets the spatial unit record corresponding to the given ``SpatialUnit`` record ``Type``.

        The ``spatial_unit_record_type`` may be the ``Type`` returned in
        ``get_record_types()`` or any of its parents in a ``Type``
        hierarchy where ``has_record_type(spatial_unit_record_type)`` is
        ``true`` .

        :param spatial_unit_record_type: the type of spatial unit record to retrieve
        :type spatial_unit_record_type: ``osid.type.Type``
        :return: the spatial unit record
        :rtype: ``osid.mapping.records.SpatialUnitRecord``
        :raise: ``NullArgument`` -- ``spatial_unit_record_type`` is ``null``
        :raise: ``Unsupported`` -- ``has_record_type(spatial_unit_record_type)`` is ``false``
