After fixing issue #99 I discovered that when I reloaded my page, I got the following stack trace from express.io:
/node_modules/cookie-parser/index.js:25
if (req.cookies) return next();
^
TypeError: Cannot read property 'cookies' of undefined

This happens because at the top of index.coffee, cookieParser is defined like this:
cookieParser = require 'cookie-parser'
Down below, we see this code:
cookieParser = cookieParser()
So the first time we come through, we call the cookieParser factory function (which takes a secret and options) and then set the result to be cookieParser. The result is a middleware function that expects 3 arguments, req, res, and next.
The next time we enter the authorization function (because of a page refresh for example), we again do cookieParser = cookieParser(). However, cookieParser is now the middleware function expecting 3 arguments. Since we pass it non, we get the stack trace seen above.
