implements SingleThreadedEventHandlerIF

Helloworld is a very simple test that introduces a programmer to self-organizing networks and event based programming. Helloworld works by a HelloWorldClient sending a HelloWorldLocateMsg to some number of HelloWorldServer. Each HelloWorldServer prints the contained msg and returns a response. That is it!
