ExtendedLogger	Extends the Logger interface with methods that facilitate implementing or extending Loggers.
LoggerAdapter<L>	A basic registry for LoggerContext objects and their associated external Logger classes.
LoggerContext	Anchor point for logging implementations.
LoggerContextFactory	Implemented by factories that create LoggerContext objects.
