> There are two reason for "chooseInitialCenters" should be move out from 
> "KMeansPlusPlusClusterer":
> # k-means++ clusterer is a special case of k-means clusterer, that k-means++ 
> initialize the cluster centers with k-means++ algorithm. Another case is 
> initialize the cluster centers with random points.
> # The mini batch k-means will reuse "chooseInitialCenters".
