// Description...: Conditions completion on the decision classes.
// Comments......: Simple (non-optimized) algorithm:
//
//                  1) Split the input table into several subtables,
//                     each containing separate decision classes.
//                  2) Do unconditoned completion for each
//                     subtable.
//                  3) Combine the completed subtables into a single
//                     table.
