/**
 * {@code MarkedLogger} is an SLF4J logger with a default marker applied to all methods with a
 * marker variant.
 * <p/>
 * Example: <pre>
 *     final Marker marker = MarkerFactory.getMarker("AUDIT");
 *     final Logger logger = new MarkedLogger(LoggerFactory.getLogger(getClass()), marker);
 *     logger.error("Missing counterparty details on order: {}", order);
 *     logger.error(marker, "Missing counterparty details on order: {}", order);
 * </pre>
 * Marks this logging event as "AUDIT".  Suitable logger configuration might redirect this event to
 * Remedy.  Both logging lines are equivalent.
 * <p/>
 * In Logback configuration use {@code %marker} to print the marker in the encoder pattern.
