This library provides Python functions for hierarchical clustering. Its features
include

    * generating hierarchical clusters from distance matrices
    * computing distance matrices from observation vectors
    * computing statistics on clusters
    * cutting linkages to generate flat clusters
    * and visualizing clusters with dendrograms.

The interface is very similar to MATLAB's Statistics Toolbox API to make code
easier to port from MATLAB to Python/Numpy. The core implementation of this
library is in C for efficiency.
