First demo of how to add logging.
Run luigid:
PYTHONPATH=. python bin/luigid
and run the example:
PYTHONPATH=. python examples/logging_example.py

log records will be sent to the daemon, which saves them in the logging directory. Visiting e.g.:
http://localhost:8082/log/ExampleSubTask(uid=7).log.txt
will show you the logs.

The demo should create all the required folders for you
