@tillrohrmann thanks for the comments, glad it's looking like it's in good
shape. I'll make these changes soon in the next few days. And thanks for the
opportunity to contribute, have also begun the approximate kNN, have almost
finished a Scala non-parallelized z-kNN for the approximate version of kNN.
