ytree 3.1 Release

Hello again!

I am very pleased to announce the release of ytree version 3.1!

ytree is an extension of yt for analyzing merger trees. This is the
second major release this month, but the last for a while as the
summer draws to a close.

The 3.1 release includes two fun new features.

• the addition of parallel iterator functions for processing trees and nodes in parallel.
• the addition of the AnalysisPipeline, a framework for creating advanced analysis workflows.

ytree can be installed with pip:

pip install ytree

Full documentation can be found at https://ytree.readthedocs.io/

Thanks as always to the fantastic yt community. Enjoy the rest of the
summer.
