+## About `common.py`
+I've copied the function inputTypeCheck() into a common.py for each directory. Normally, I would've made it a module, but to avoid system specific bugs, I've decided not edit global environment variables like PYTHONPATH or edit the sys.path. This means, at least as far as I know, that I can't use relative imports.
