   Message

   The type of message being received, which must be Any for akka.actor.Actor, and must be the same type of T for akka.actor.typed.Behavior.

   Example:

   1. This ReceiveMessage keyword can be used in the akka.actor.Actor.Receive domain, to receive the next message. The above code creates an actor to echo any messages.

      import com.yang_bo.dsl.keywords.akka.actor.ReceiveMessage
      import akka.actor._
      def echoActor = new Actor {
        def receive: Receive = {
          while (true) {
            val lastMessage = !ReceiveMessage[Any]
            sender() ! lastMessage
          }
          throw new Exception("Unreachable code!")
        }
      }
      val pinger = system.actorOf(Props(echoActor))
      pinger ! "hello world"
      expectMsg("hello world")

      All messages that are not the class of Message will not be handled.

      pinger ! "string message"
      expectMsg("string message")
