	TIC-TAC-TOE
	by Evan Hahn (http://www.evanhahn.com/)
	
	This is a program that allows you to play tic-tac-toe against the
	computer.
	
	You may change the configuration (below) to make the board more than 3x3,
	or play with "white" and "black" instead of "x" and "o", and change how

# Non-destructive quicksort.
# DOESN'T WORK WITH DUPLICATES. Too lazy.
# [1, 5, 8, 12].quickSort()
Array::quickSort = ->

	# Is the array already sorted by nature of its length?
	return this if @length <= 1

	# Pick a pivot as a random element.
	# This is probably not the best pivot we could choose.

# Non-destructive merge sort.
# [1, 8, 12, 5].mergeSort()
Array::mergeSort = ->

	# If the array has one element, we're done.
	return this if @length is 1

	# Split the array in half.
	halfwayMark = Math.floor(@length / 2)
	firstHalf = @slice(0, halfwayMark)
