QueryKNearest
returns the results in order, furthest to closest. This should be mentioned somewhere at the very least. This caused me so manny headaches until I said let's try it in reverse see what happens.
Errors and crash when using an updated version of the "Collections" package.
I didn't try to fix it for now, I will look into it.
Thanks!

When building a tree, the right node is split if the left node is large enough, and vice versa. I assume this is not intentional and the node is supposed to be split based on its own size.

I found a bug when trying to get point cloud neighbors of mesh vertices.
I join a script that parses a file and compute the neighbor search to this issue.
