Fixed calculation of KBRelativeInformation. Improved Javadoc description of SF entropy scores. priorEntropy() now just returns SFMeanPriorEntropy(). It previously returned the entropy of the last batch of data used in setPriors(). KBRelativeInformation is slightly different from the formula in the KB paper because we are not using mean log-loss on the training data wrt to the class priors from the training data: we use the mean log-loss for the test data (which could be the training data) wrt to the class priors now. The previous calculation of the KBRelativeInformation score was incorrect anyway.
