Class RankFeatureSaturationFunctionDescriptor

Gives a score that is equal to S / (S + pivot) where S is the value of the rank feature and pivot is a configurable pivot value so that the result will be less than 0.5 if S is less than pivot and greater than 0.5 otherwise. Scores are always is (0, 1). If the rank feature has a negative score impact then the function will be computed as pivot / (S + pivot), which decreases when S increases.
