// Description...: For each rule that fires, a trace is made back to
//                 which object(s) the rule was derived from. The
//                 set union of these tracked objects is computed,
//                 and the final voting is done on the basis of this.
//                 In effect, this means that the originating objects
//                 do the voting (with one vote each), and the set of
//                 objects that get to vote is defined through the set
//                 of rules that fire.
