EM example: K-means
-------------------
Figure 6.13

The K-means analysis of the stellar metallicity data used in figure 6.6. Note
how the background distribution "pulls" the cluster centers away from the locus
where one would place them by eye. This is why more sophisticated models like
GMM are often better in practice.
