[Feature Request] Comparing trees

[netthier]

There currently seems to be no way of determining if two trees contain the same points and values. This could be implemented by implementing something like IntoIterator over all points for KdTree, which can then be collected, sorted and compared by the user.

Thanks for the suggestion. You're correct, there's no way to do this at present, but I don't see it as being too difficult to implement. Effectively an iterator where each entry in the iterator is a tuple of each item's co-ordinates and node content.

I'll add this to the backlog - also happy to accept pull requests for implementations of this 👍🏼
