%description
Performs minimax linkage hierarchical clustering.  Every cluster has an
associated prototype element that represents that cluster as described in
Bien, J., and Tibshirani, R. (2011), "Hierarchical Clustering with
Prototypes via Minimax Linkage," The Journal of the American Statistical
Association, 106(495), 1075-1084.
