Python logging example

A demonstration of how to use the python logging module across a main and sub module. In this example the logging level verbosity is set at the entry point.

Also included is a custom log level (dev) that sits between the info and debug levels (integer value 15). To enable this level, the module containing the log_dev setup should be imported (and not necessarily have any functions called).

>>> python3.9 main.py
