Pretty simple to set up and use, but I'm not sure if it's better than learning `docker` and `docker-compose`. Also, the default `python <file>.py` doesn't remove the container after the file is done running and the image is tagged as `cage/<name of project>` instead of allowing the user to tag it with their own name. Both of these are easy to fix with `docker` commands, but if this is meant to be a library that helps you avoid `docker` then it's not doing its job.
