scipy: BUG: Cannot get rid of Deprecation Warning with cKDTreeNode

Describe your issue.

Cannot get ride of Deprecation Warning with cKDTreeNode As cKDTreeNode is not exposed at the root of scipy.spatial

Reproducing Code Example

import scipy.spatial.ckdtree

scipy.spatial.ckdtree.cKDTree()     # fixable!
scipy.spatial.ckdtree.cKDTreeNode() # not fixable!

# to fix it,as the Deprecation Warning states

import scipy.spatial
scipy.spatial.cKDTree() # fixes it!
scipy.spatial.cKDTreeNode() # errors out

The problem is that cKDTreeNode is not exposed in scipy.spatial
python -c "import scipy.spatial; print( scipy.spatial.cKDTreeNode )"
AttributeError: module 'scipy.spatial' has no attribute 'cKDTreeNode'

Error message

DeprecationWarning: Please use `cKDTree` from the `scipy.spatial` namespace, the `scipy.spatial.ckdtree` namespace is deprecated.

Sure, but I will need to get up to speed on how to submit a PR first 😃 Maybe is the my time to get into open source software contributions after all…

as an information, I am using that class (cKDTreeNode), as it is returned by the code, so I am doing type checking. I checked and cKDTreeNode is not derived from cKDTree, otherwise I would just used cKDTree.
