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 gather information of some number of HelloWorldServer. Then HelloWorldClientget back the infomation and send a msg to some number of the cloest HelloWorldServer After receiving the message, HelloWorldServer prints the contained msg and returns a response. That is it!
