Uses Buffer to emulate the exact functionality of the browser's atob.

Note: Unicode may be handled incorrectly (like the browser).

It turns base64-encoded ascii data back to binary.

(function () {
  "use strict";

  var atob = require('atob');
  var b64 = "SGVsbG8sIFdvcmxkIQ==";
  var bin = atob(b64);

  console.log(bin); // "Hello, World!"
