//groupselect mods

//
//                       groupselect
//                     (CL,pk->id)
//
// Meaning: pk->primary key field of the table
//          fk->foreign key to link with parent
//          nt->nested field (recursive data)
//          CL->course level info
//          UL->user level info
//          files->table may have files)
