Sorry, may be my expression below was not clear.
My purpose(of prediction) is to find a proper cluster for a new point, and then
add the point to cluster, or further find out the top N nearest points in the
proper cluster.
Return a int[] of indexes may better, for both can used to find the proper
cluster, and find out the top N nearest points in a cluster.

> 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".
