On: Add variables to Python traceback

[pininja]

Opening an issue to ask for a FAQ comparison might help people evaluate the differences.

For those like me who didn’t know about this: https://docs.python.org/3/library/cgitb.html

While the function seems similar, the interfaces seem very different. cgitb seems to need to be wrapped and configured to match the fully headless/logger use case. I think they could focus on that in the FAQ.
