 *  An implementation of InternalLogger that passes all messages
 *  to the Logback status buffer.
 *  
 *  Instances are provided with the destination for log messages. This is normally
 *  the appender itself, and the status buffer will use the appender's class and
 *  name in all logging messages. For non-appender use (eg, JMXManager), you will
 *  need to provide a destination.
