Yet another Python implementation of collapsed Gibbs sampling for Latent 
Dirichlet Allocation 
(http://en.wikipedia.org/wiki/Latent_Dirichlet_allocation),
as described in

	Griffiths, T. L., & Steyvers, M. (2004). Finding scientific topics. 
	Proceedings of the National Academy of Sciences, 101, 5228-5235

Though other implementations already exist, I wanted to write my own for the
sake of understanding the algorithm.

Runs much more quickly with PyPy (http://pypy.org/).
