Create a consumer interface users can extend

[agaro1121]

Maybe something like this:
So users are forced to process events and not have to worry about a receive method

import com.weightwatchers.core.eventing.consumer.ConsumerWorker.{EventProcessed, ProcessEvent}
import akka.actor._

abstract class AbstractConsumerActor extends Actor {

  def processEvent: Function[ProcessEvent, EventProcessed]

  def send: EventProcessed => Unit

  val processAndSend = processEvent.andThen(send).asInstanceOf[PartialFunction[Any,Unit]]


  override def receive: Receive = processAndSend
}

extending it would look like:

class TestConsumer extends AbstractConsumerActor {
  override def processEvent: Function[ProcessEvent, EventProcessed] = ???

  override def send: (EventProcessed) => Unit = ???
}
