+An Akka `Source` is provided that can be used with streams. It is possible to create a source from a `ConsumerConf` or 
 directly from the consumer name that is defined in the configuration.
 Every message that is emitted to the stream is of type `CommitableEvent[ConsumerEvent]` and has to be committed 
 explicitly downstream with a call to `event.commit()`. It is possible to map to a different type of `CommittableEvent`
