Create openbugger_example.ipynb

[furlat]

Added an example for OpenBugger that can bug python code either in string or from a imported class to generate training samples for interactive code debugging. The code will clone https://github.com/furlat/OpenBugger and pip install the package to load the SyntaxBug and LogicBug classes.

Thank you very much! could you add a small markdown file like the other notebooks have? just so people can see what's in there in case they don't have a jupyter running or aren't on github. it can be super brief.

Added the md I hope is fine
