simulated

This is supertest minus the assertions & expectations,
used to simply mock API calls (when passed an express app instance)
in an easier fashion than invoking the native express router.
Big thanks to TJ.

```js
simulated(app)
.get('/endpoint')
.end(function(err, response){
//
// i.e. use inside of socket.io connection,
// make call without frontend XHR
//
if (response.error.status === 404) {
socket.emit('news', response.error);
} else {
socket.emit('news', response.body);
}
});
