     ☐ Can prospector ignore tests dir? document this in the gist if so
     ☐ Redo the documentation on a CLI, reorganise and inocropoate all the new tembo layouts

+            Use `importlib.reload(module)` in each test instead of explicitly importing the module.

 Functionality:
     ☐ Replace loggers with `click.echo` for command outputs. Keep logging messages for actual logging messages?
