        public PermutationSampler​(UniformRandomProvider rng,
                                  int n,
                                  int k)
        Creates a generator of permutations.

        The sample() method will generate an integer array of length k whose entries are selected randomly, without repetition, from the integers 0, 1, ..., n-1 (inclusive). The returned array represents a permutation of n taken k.

        rng - Generator of uniformly distributed random numbers.
        n - Domain of the permutation.
        k - Size of the permutation.
        IllegalArgumentException - if n <= 0 or k <= 0 or k > n.
