Feature Request: non command line version

[WolfgangFahl]

We'd love to use radb for our database course at RWTH Aachen i5. It would be great if it would be possible to interact with radb without a command line so that the integration with our jupyter notebooks can be improved.

For a start i suggest it would be great to start with a test-first approach and add some python unit tests to the project. This way you could e.g. also automatically test the project with a continuous integration approach.

That's great suggestion. I haven't found the cycles to do this myself though. I hope somebody can take a shot at it.
