-console.log(emoji.which(emoji.get('coffee'))); // returns the string "coffee"
-console.log(emoji.get(':fast_forward:')); // `.get` also supports github flavored markdown emoji (http://www.emoji-cheat-sheet.com/)
-console.log(emoji.emojify('I :heart: :coffee:!')); // replaces all :emoji: with the actual emoji, in this case: returns "I ❤️ ☕️!"
