Note that if `make` is run with targets like `build`, `up`, or `test`, that image will be rebuilt by Docker using the local code, and tagged as `latest`.

 As this project uses a `src` [folder structure](https://blog.ionelmc.ro/2014/05/25/python-packaging/#the-structure), so under _Preferences > Project Structure_, the `src` folder needs to be marked as "Sources".  That will allow the interpreter to be aware of the package from folders like `tests` that are outside of `src`. When adding Run/Debug configurations, make sure "Add content roots to PYTHONPATH" and "Add source roots to PYTHONPATH" are checked.
