public boolean export(File file, DomainFile domainFile, TaskMonitor monitor)
			throws ExporterException, IOException {
		throw new UnsupportedOperationException("DomainFile export not supported");
	}
Actually does the work of exporting a domain file, if supported (see
{@link #canExportDomainFile(DomainFile)}).  Export is performed without instantiation of a
{@link DomainObject}.

@param file        the output file to write the exported info
@param domainFile  the domain file to be exported (e.g., packed DB file)
@param monitor     the task monitor
@return true if the file was successfully exported; otherwise, false.  If the file
  was not successfully exported, the message log should be checked to find the source of
  the error.
  
@throws ExporterException if export error occurs
@throws IOException if an IO error occurs
