+Modernize packaging strategy. Use pyproject.toml for environment definition. Save environment files at the

+
+Simplify test workflow. Run tests on python 3.11-3.13. (#859)
+
+Remove requirements.txt file. (#260)
+
+Comment out batman package from pyproject.toml. batman requires distutils, which has been removed from
