ClusterStability        Calculates the approximate stability score
                        (_ST_) of individual objects in a clustering
                        solution (the approximate version allowing one
                        to avoid possible variable overflow errors).
ClusterStability-package
                        Assessment of the stability of individual
                        objects, clusters and a whole clustering
                        solution based on repeated runs of a clustering
                        algorithm.
ClusterStability_exact
                        Calculates the exact stability score (_ST_) for
                        individual objects in a clustering solution.
Kcombination            Kcombination returns the list of all possible
                        combinations of a set of numbers of a given
                        length _k_.
Reorder                 This function returns the ordering of a
                        partitioning solution in ascending order.
Stirling2nd             Stirling2nd function computes the Stirling
                        numbers of the second kind.

calinski_harabasz_score
                        This function returns the Calinski Harabasz
                        score.
davies_bouldin_score    This function returns the Davies Bouldin score.
dunn_score              This function returns the Dunn_score.
