// Description...: Takes a decision table as input and splits it
//                 into several subtables.
//
//                 If specified, the resulting subtables are appended
//                 to the input table as children, and the input table
//                 itself is returned.  Alternatively, the subtables are
//                 not appended as children, but are instead returned as
//                 a decision table set.
