class TanimotoDistanceMetric extends DistanceMetric

This class implements a Tanimoto distance metric. The class calculates the distance between the given vectors. The vectors are assumed as bit-wise vectors. We convert the result of division to a usable distance. So, 1 - similarity is actually returned.
