Shuffle Visualizer: Visual sanity-check for randomness in deck-shuffling algorithms (JS and CoffeeScript versions)
#Usage:
#1. Declare your shuffle() function. No parameters necessary, since `deck` is a global variable.
#2. Run `test()`.
deckSize = 52
deck = [0...deckSize]
rand = (min = 0, max = deckSize) ->
Math.floor(Math.random() * (max - min)) + min
