Analysis of kmeans-based cluster results.

This is a Python implementation of cluster quality metrics as described in:

Braun E, Geurten B, Egelhaaf M (2010) Identifying Prototypical Components in Behaviour Using Clustering Algorithms. PLoS ONE 5(2): e9361. doi:10.1371/journal.pone.0009361

The original source code given by Braun et al is included, as is a Python implementation of the same quality metrics. Included unit tests ensure that the two implementations produce the same results.

The postcluster library is open sourced, and is licensed under the GPL v 2 or later.
