materialsproject/pymatgen v2022.0.1

Namespace package version

on GitHub

pymatgen, pymatgen.ext, pymatgen.io and pymatgen.analysis are now
namespace packages. Note that this does not affect normal usage of pymatgen
from v2022.0.0. All imports remain the same. However, it does allow developers
to write "add-ons" to these subpackages. A full documentation with examples
and templates is in the works to guide developers on how to write these
packages.
