Subject: [PATCH 06/24] WIP: Created some basic controllers for the UI and
 started implementing backend for server stuff

Created GameState Class. Static, contains all info about current state of game: list of players and their respective details (coords etc) also Host info

Clients will observe this GameState class

Upon pressing host, new GameState is created and new GameConnectionListener created which listens for connections

Player class created which will be used to take each connection and store it as a player with other info about them regarding the game in the GameState class

Subject: [PATCH 07/24] Researched and implemented a way for the game to listen
 for key presses. When one of the valid key controls are pressed, feedback is
 given in the console. Has yet to be connected to a method which will create
 and send a message to the server.

Subject: [PATCH 15/24] Added garbage collection for disconnected players

- Heartbeat messages are sent out from their own thread to each player
- If a heartbeat message can't be sent to a player, they are removed from the list of players
- Added equals method for players

Subject: [PATCH 17/24] WIP: Worked on new server thread class that would
 create and store multiple THREADS of connections. Researched Authorative
 server structures. Fixed the current structure of the server to work with the
 old StreamReciever style and hook up to the Stream Parser

From: Zhi You Tan <zyt10@uclive.ac.nz>
Date: Fri, 14 Jul 2017 18:23:07 +1200
Subject: [PATCH 18/24] Implemented a more reliable way for keystroke input and
 added boat action packet type so stream parser is able to read and decode the
 message appropriately.

Subject: [PATCH 21/24] WIP: Implemented a temporary workaround to send an
 instance test to client server upon connection. Still needs reengineering to
 change socket channels for sending to ouput stream in the message class. Only
 client to server "working".

From e83eaa38e182cbdc312cea1d73f32f3df7d61998 Mon Sep 17 00:00:00 2001
From: William Muir <wmu16@uclive.ac.nz>
Date: Tue, 18 Jul 2017 12:22:58 +1200
Subject: [PATCH 23/24] Upon hosting, and then creating a new instance and
 connecting to that IP, button transmissions work and print out on server!! :D
 Took the send method out of the Message class as it didnt make sense to have
 it there. This meant taking it out of all subclasses too
