need more specific use of logging

[mheilman]

Currently, the code just uses logging.info, logging.warning, etc. to record log messages. It would be better to instantiate one logger for the module, or logging modules for each class, etc. I'm not sure what the best way to do this is, but it would be best to do this without adding a ton of code to every class.
