k-means should support better handling of empty clusters #595

We should update the KMeans class so that the EmptyClusterPolicy and only the EmptyClusterPolicy controls what is done with empty clusters. Two options I plan to implement are:

  • "kill" the cluster by setting it to all DBL_MAX, so it's never used again
  • leave the cluster alone, by simply leaving the centroid in place; this is Erich's (@kno10) suggestion

This comes out of the discussion for #592.
