How to do it...

1. Create a file called ActorLifeCycle.scala in package com.packt.chapter2.
2. Add the following imports to the top of the file:

        import akka.util.Timeout 
        import scala.concurrent.Await 
        import scala.concurrent.duration._ 
        import akka.pattern.ask 

3. Create the following messages to be sent to the actors:
