This primarily adds the convergence tool to the package but also includes some minor updates:
Improved method of detecting binary columns when generating the cluster multi_clust object.
Update titles of plots to reference "K Clusters" (e.g. rather than title "Within Sum of Squares by Cluster" it's now "Within Sum of Squares by K Clusters"). This should remove any confusion that we're plotting cluster number for a single run, not number of clusters.
Fixes the % variance reported by the PCA plot (it was reporting variance of the first 3 components, when it should have been the first 2 components).
