 * Convenience class for constructing various {@link LogstashMarker}s used to add
 * fields into the logstash event.
 * <p>
 * This creates a somewhat fluent interface that can be used to create markers.
 * <p>
 * For example:
 * 
 * <pre>
 * {@code
 * import static net.logstash.logback.marker.Markers.*
 *     
 * logger.info(append("name1", "value1"), "log message");
 * logger.info(append("name1", "value1").with(append("name2", "value2")), "log message");
 * logger.info(appendEntries(myMap), "log message");
 * }
 * </pre>
