* This is where the Client and Server connect() functions are called. The Server is powered on and waits for a connection 
* and the Client(s) are able to connect. There is also a displayHelp() method added in to help a user understand how to start 
* Client/Server if they are having difficulties starting the program. If the command line recieves 3 arguments then it knows 
* that it is the Server. if the command line recieves 4 arguments then it knows that it is the Client,
