"""
Return a balanced k-ary tree topology of with depth h
Each node has two attributes:
* type: which can either be *root*, *intermediate* or *leaf*
* depth:math:`(0, h)` the height of the node in the tree, where 0 is the
root and h are leaves.
Parameters
----------
k : int
The branching factor of the tree
h : int
The height or depth of the tree
Returns
-------
topology : A Topology object
