      public SampleCategoricalDistribution​(List<dk.alexandra.fresco.framework.DRes<dk.alexandra.fresco.lib.fixed.SFixed>> probabilities, boolean normalized)
      Parameters:
      probabilities - The i'th element of this list is the probability of drawing i from this distribution.
      normalized - Does the probabilities sum to 1? If not, the computation handles the normalization.
