A model of the concept Neighbor Weighting Method to be used with KNN to weight the votes of the k nearest neighbors of a sample.
KNN_ReciprocalRank weights the vote of a nearest neighbor with its reciprocal rank. The class of the nearest neighbor gets the vote 1/1, the class of the second nearest neighbor gets the vote 1/2, and so on

The total vote for each class is calculated and returned in prediction.
