+ # Middleware are wrapper functions around the main app function. They
+ # have 3 arguments (app, req, res) instead of the regular two (req, res)
+ # and return a function that accepts the regular two like a normal app.
+ # However that function exists within the 3-argument closure and calls the
+ # closured app function after doing its modifications to the req/res.

+ # The suggested means of action for middleware is to modifiy the req.env
+ # dict to send/receive data from the app.
