Bingo Card Maker: A First-Try with Coffee/JavaScript

A bingo card creator for teachers which turns a list of questions and answers into bingo cards including a randomised sheet for the caller which also indicates when each bingo card will win for speedy vaildation of winning cards. This one-page utility was my first try at writing something in CoffeeScript/Javascript. Please do not judge me for the code!
