Battleship Doodles

You should have the following classes:

Administrator - who oversees the running of the whole game

Player - 	who is guessing the ship's positions

PlayerInfo - 	which records the results so far and generates next guess

Enemy - 	who is responding to guesses

EnemyInfo - 	which records the current ship's positions 
		and generates the responses to guesses

IOChannel - 	which is used to communicate the messages between the Player and Enemy - 
		under the control of the Administrator
			this is an interface - 
				we implement it as console, 
						   server socket,
						   client socket
						   GUI (if I find the time to do it)



Administrator contains:
	Player
	Opponent
	IOChannel

Administrator has the following methods:

	openGame() - 	initialize Player and Opponent
			define IOChannel object - can be console, GUI, or socket
			open the channel
			establish communications
			determine who goes first

				if (myturn) - call myGuess()
				else        - call yourGuess()
			if unable to initiate the game - call shutDown()

	myGuess() - 	Player.playTurn()
			if not win, channel not closed - yourGuess()
			else - shutDown()

	yourGuess() - 	Opponent.playTurn()
			if not win, channel not closed - myGuess()
			else - shutDown()

	shutDown() -	record the winner, final messages

Player contains:
	PlayerInfo
	IOChannel

Player has the following methods:

	initialize() - 	whatever is needed to set up the board, etc.

	playTurn() - 	PlayerInfo.selectGuess() - to select next guess
			write guess-message to the channel
			read reply-to-guess-message from the channel
			PlayerInfo.processResult() - to record the results
			write your-turn-message to the channel
			return info about win

Opponent contains:
	OpponentInfo
	IOChannel

Opponent has the following methods:

	initialize() -	set up the board with ships - either via user interactions
			or at random, or using some mathematical strategy

	playTurn() - 	read guess-message from the channel
			OpponentInfo.processGuess() - to see if hit, miss; win
			write reply-to-guess message to the channel
			read your-turn-message
			return info about win

IOChannel interface has the following methods:

	open() - 	open the channel - 
				return true if successful
				return false if failed to open

	read() - 	return String read from the channel

	write(String) - write the given String to the channel

	close() - 	close the channel
	

Message formats - so we can play against each other:

guess-message:

guess(2 3)
guess(10 3)
guess(4 10)
guess(10 10)

reply-to-guess-message:

integer with values 2 through 5 - corresponding to the constants MISS WIN HIT REPEAT

your-turn-message:

String "Your turn"
