[SciPy-Dev] Faster implementation of cluster.hierarchy

[Travis Oliphant]

This looks very cool.  If we can get the BSD license then it would be perfect for integration into SciPy

It would be best of you could use Cython for the integration work.  

You can fork the SciPy project on github and start making your changes using another package's setup.py as an example. 

Thanks for your contributions.

Best,

Travis

Rather than integrate the code in scikit-learn, it seems more appropriate to integrate it upstream in scipy.cluster.hierarchy.  Is there anyone who is interested in this integration?  I am inexperienced with integrating C++ code and python code, and also with how things work in the scipy project, so I'm not sure how to proceed.
