Comparator<Rule> joshua.decoder.ff.tm.Rule.NegtiveCostComparator

Initial value:

 new Comparator<Rule>() {
    public int compare(Rule rule1, Rule rule2) {
      float cost1 = rule1.getEstCost();
      float cost2 = rule2.getEstCost();
      if (cost1 > cost2) {
        return -1;
      } else if (cost1 == cost2) {
        return 0;
      } else {
        return 1;
      }
    }
  }

In order to provide sorting for cube-pruning, we need to provide this Comparator.
