BASIC FEATURES
--------------

Simple Javascript representation of a Go board:
	Started: go.js
	Simplify Code
	Wrap in a Go object or JS class
		Depends on:
			Recode in CoffeScript ??
				or
			Code for Node ??
				or
			Both: Node and CoffeeScript (Zappa)
	Use Array (or set) generator/consumer instead of recursion:
		Add Tests
		go.js:
			 @checkNonRec(r,c,p)
				vs.
			 @checkRec(r, c, p, fcn)
		May need to add to Array.prototype for IE:
			@indexOf
			@filter
			@map
			@reduce

Represent Go Game:
	Objects:
		Two active players: White and Black
		stones: White and Black
		Board Size: 
			5x5: DONE
			9x9: DONE
			13x13: DONE
			19x19: DONE
	Legal Moves
		Surrounded stones
		Captured stones
			@zap(row,col)
			@moveAndCapture(cell): deleted
			@findCaptures(r, c, p) and @canCapture(r,c,p)
		Eyes & Covered Eyes
		Cannot capture own stones (illegal move)
			DONE
		Pass
		End game: both players Pass.
			SOON
	Go Terms (optional):
		Chains:  two or more stones of the same color that are placed next to each other (non-diagonally).

		Living stones: group that cannot be killed (two or more eyes).
		Go capture: play go until first stone is captured.
	More Advanced:
		Winning & Quiting
		Ko: cannot make a capture that brings the board right back to where it was before.
		Handicap Stones
		Scoring
			Chinese: number of living stones + eyes
			Japanese: number of captured stones + territory
		Komi: bonus points
			White player given 6.5 points of Komi since goes second
		Time Limits ??

Display Game:
	Forms for user input:
		Player:
			User Name
			Color (Black or White): go.html
			Skill Level??
		Chat
		Quit Button
		Timer??
	Canvas Tag for Displaying Go Game: gocanvas.js, go.html
		Click to place stone
		Confirm button needed ??
		Use excanvas for IE7 : js/excanvas.min.js
		Fallback to HTML or use browser upgrade message/link to IE9 ??
		Grid Lines: 
			Middle line instead of border lines
				Click on crossroads instead of center of square

ADVANCED FEATURES
--------------

Go Game Server:
	Separate Project
	Use Zappa or other framework
	Two players (default)
	Options/Advanced:
		Viewers for public games 
		Multiple games per server 
		Use online Go standards to make interoperable ??

AI:
	Making a computer be a really good Go player is
	known as a Hard Problem in Artificial Intelligence circles.
	Much more difficult than Chess because so many more positions
	Probably requires specific and general pattern recognition
	Look at:
		Surreal Numbers
		Neural Nets
		Fuzzy Logic
		Pattern Recognition
		Visual/2d Pattern Recognition
	Look for expert help:
		Expert AI Programmers
		Go Masters

Mobile Version:
	Wrap in WebView
	Gestures & buttons
		Easily Zoom in & Out
		See see last move
