It is a simple Client-Server model that uses TCP to share messages between clients
-> Two clients can talk two eachother simultaneously
-> TCP connection is used (only standard lib)
-> One message has a word length of 250 characters
-> Everthing happening here, like the Input from the user, sending input to server, receiving input from server are handled in seperate threads
