    @tillrohrmann BTW, I have fixed that issue with the center, realized I can just pass a `copy` of `center` to `PartitionBox`.  Both the `KNNITSuite` and `QuadTreeSuite` are passing now.

> Even though the k-nearest-neighbours (kNN) [1,2] algorithm is quite trivial it is still used as a mean to classify data and to do regression. This issue focuses on the implementation of an exact kNN (H-BNLJ, H-BRJ) algorithm as proposed in [2].
> Could be a starter task.
