Logbook 0.4.1

The basic interface is similar to the standard library’s "logging" module.

Here are some key features of "Logbook":

Logging levels:
· critical – for errors that lead to termination
· error – for errors that occur, but are handled
· warning – for exceptional circumstances that might not be errors
· notice – for non-error messages the user usually wants to see
· info – for messages usually the user doesn’t want to see
· debug – for debug messages
