Package logger implements a multi-output leveled logger.
Other packages use tagged logger to send log messages to shared
(process-wide) logging engine. The shared logging engine dispatches to
multiple log systems. The log level can be set separately per log
system.
Logging is asynchronous and does not block the caller. Message
formatting is performed by the caller goroutine to avoid incorrect
logging of mutable state.
