Title: Minimal Port of Express.js Route Param Pre-conditions

Minimal port of the functionality offered by Express.js [Route Param Pre-conditions](http://expressjs.com/guide.html#route-param%20pre-conditions)

This basically piggy-backs on the `server.use` method. It attaches a new middleware function that only fires if the specified parameter exists in `req.params`

This might be _too_ simplistic, if so I can beef it up a bit. :)
