To Do

This is a list of issues I need to address at some point:

• Cluster can only get one version at a time.
• GetVersion message can be sent by multiple nodes and "pass each other in the cloud."
• The wrong port number is written to cluster.json
• Sometimes two Json messages are sent in the same packet
• NodeReadyState needs to handle the ConnectionClosedMessage
• Null hostname in connectTo
• Test com.ltsllc.miranda.cluster.Cluster.contains
• Resolve the problem where the FileWatcherService wants access to MirandaProperties before the Writer has started.
• SingleFileReadyReadyState's implementation of processGarbageCollectionMessage is wrong: it should check for "garbage" users, topic, and suscriptions.
• Replace all uses of System.exit with panic.
• Implement or get rid of SocketHttpServer.addServlets and NettyHttpServer.addServlets
