@abc.abstractmethod<EOL><INDENT>def supports_unit_types_for_conversion(self, source_unit_type, target_unit_type):<DEDENT>
return<EOL>
Tests if a given measure conversion is supported.

        :param source_unit_type: the type of the source measure
        :type source_unit_type: ``osid.type.Type``
        :param target_unit_type: the type of the target measure
        :type target_unit_type: ``osid.type.Type``
        :return: ``true`` if the given source and target conversion is supported, ``false`` otherwise
        :rtype: ``boolean``
        :raise: ``NullArgument`` -- ``source_unit_type`` or ``target_unit_type`` is ``null``
