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
