.calculateLogProb       Calculates the log probability of seeing a
                        given set of preferences
.estimateEntropy        Calculates the expected posterior entropy of
                        the prefel object if x and y are compared.
                        Ignores the odds of indifference preferences,
                        as using them would increase runtime 50%
                        without much gain.
.getLogIndifProb        Evaluates the likelihood of the observed
                        indifference preferences
.getLogStrictProb       Evaluates the likelihood of the observed strict
                        preferences
.sampleEntropy          Calculates the entropy of a matrix of samples.
