setup rudimentary project structure

please have a look at the rudimentary project structure.

The Makefile is a shortcut for linting. Just run

make check

to check your code or

make black

to let black format it. That's also documented in the README.md.

We use a line length or 96 in other projects. But I'm open for anything between 80 and 120. Thoughts?
