Tests if a given spatial unit conversion is supported.

        :param source_spatial_unit_record_type: the type of the source spatial unit record
        :type source_spatial_unit_record_type: ``osid.type.Type``
        :param target_spatial_unit_record_type: the type of the target spatial unit record
        :type target_spatial_unit_record_type: ``osid.type.Type``
        :return: ``true`` if the given source and target conversion is supported, ``false`` otherwise
        :rtype: ``boolean``
        :raise: ``NullArgument`` -- ``source_spatial_unit_record_type`` or ``target_spatial_unit_record_type`` is ``null``
