Segmentation fault on empty points

[STNLd2]

Please add a check for empty point array in KDTree input.

tree = KDTree(np.array([]))

falls with the segmentation fault.

@STNLd2 thanks for bring this to our attention! is this anything you are willing to provide a fix for?

@mraspaud Could you take care of it? Don't want to mess with forking just for 2 lines of code :)

@STNLd2 I know that @mraspaud is getting ready to go on holiday so he might not have time for this. I know I don't right now either. Since you found the issue, filed the bug, and have the use case where you'd like this check, it may be best for you to tackle this. And it wouldn't be just 2 lines of code because this could use a test in the test_tree.py module too.

Sorry, I've just noticed the last message.
I see. I'll do it.
