For the method
bool FFRequestHandler::ff_build_data(BESDataHandlerInterface & dhi)
Test the MDS to see if a DDS response for the dataset referenced by the DHI is present. If not, continue as the code is now. If a DDS is present in the MDS, get that DDS and it’s matching DAS and parse them to build DDS/DAS objects. Use the FreeForm handler factory class with the parser. Return this DDS after merging in the DAS information.
