From the tree docs:

> tree has originally been part of TensorFlow and is available as tf.nest.

The tf.nest docs can be found here and may be more useful for now: https://www.tensorflow.org/api_docs/python/tf/nest

I'm glad this is being moved out of TensorFlow. It's a really useful library on its own and I've found myself reaching for it on projects without wanting to import all of TensorFlow.

I wonder what is the utility of this library?
