* Move tests to root with automatic PyCharm import refactoring. This will likely fail some tests * Changed entry point for a registration test env. * Move a stray lunar_lander test to tests/envs/... * black * Change the version from which importlib_metadata is replaced with importlib.metadata. Also requiring installing importlib_metadata for python 3.8 now. ??????????? * Undo last commit
