@MLnick I checked and adding the `computeCosts` to `ClusteringEvaluator`
has a small drawback: we have to compute the centers for each cluster and then
we can compute the costs, which involved two passes on the dataset.
Since this and that this evaluation looks not very useful in practice, is
it worth according to you to add it nonetheless?
Thanks.
