Add Dockerfile and docker-compose.yml

[Otto-AA]

What was wrong?

Nothing wrong per se. I didn't want to install all the dependencies directly on my computer (an old python version, etc.).

How was it fixed?

I've wrapped it in a Dockerfile. I'm not very familiar with docker, so I guess it's not the cleanest. However, I think it's at least a good starting point, for me it would have saved a few hours.

Usage instruction is added to the README

To-Do

• add documentation how to use this in production (I don't plan to look into this)
