Log Message:
-----------
Add some convenience methods to determine/set logging level for a
logger, and one to determine if a given log level will emit.

Also, determine whether to emit in emit(), though dreid will tell me
we need to move this to the observer, which will happen when I learn
how 'n stuff.
