 * This class is used by the combine-from-hub.sh program.

 * and creates a new TOIMPORT.nl file with the DCPs from this 
 * XML Network List minus any DCP found on the controlling-district
 * file.
 *
 * This utility will be used when the combine-from-hub.sh can't find
 * a district-TOIMPORT.nl file, in which case this class will create
 * the district-TOIMPORT.nl file for the given Network List XML file.
 * This will be used when adding a new group to the combine SQL Database.
