   A KafkaStreams Transformer offering an upgraded API over the built in Transformer interface.

   This Transformer differs from the built in Transformer interface by exposing an [onMessage] interface that is used to process incoming messages. Within [onMessage] you may use the [forward] method to emit 0 or more records.

   This transformer also manages watermarks(see [WatermarkManager]), and extends [OnWatermark] which allows you to track the passage of event time.
