> The multi-version of {{getChildren}} function allows us to traverse a tree using fewer
requests to the server. At the moment, the number of requests for traversal is the same as
the number of nodes, however, this can be changed to only use up as many requests as the height
of the tree.
> Currently, {{listSubTreeBFS}} utility function used for the deleteAll command and this
improvement makes it more robust, especially in high latency setups.
