 * CambridgeSoft did a fabulous job on the specification.

 * This reader extends CDXMLWriter. It simply passes the CDX binary to CDXMLWriter,
 * which returns the XML. The XML is then passed through the CDX files on the
 * fly to CDXML and then processes those using the XMLChemDrawReader.
 * 
 * Note that CDXMLWriter, though public, is not exposed generally, as it is only a skeleton class intended to get just enough of the job done to
