Re-evaluate logging configuration

[piehld]

Currently, we turn on logging and set the default configuration to WARNING level. However, by doing this, there is a chance that this will incidentally take precedence and prevent users from re-configuring their logger in another application. So, we should re-evaluate whether we should be configuring it here, or switch certain logging messages to print statements instead.
