/**
* Example Waif service.
*
* Waif services are standard express apps, but instead
* of listening to a connection on their own, they export
* the app object.
*
* These apps are going to be mounted in express, but
* they can actually be anything that conforms to the
* behavior of connect middleware.
*
* You can probably get away with just Express.Router
* most of the time.
