 * api/responses/notFound.js
 * 404 (Not Found) Handler
 *
 * Usage:
 * return res.notFound();
 * return res.notFound(err);
 *
 * NOTE:
 * If a request doesn't match any explicit routes (i.e. `config/routes.js`)
 * or route blueprints (i.e. "shadow routes", Sails will call `res.notFound()`
 * automatically.
 *
 * Based on JSend responses, with a small variation on failed responses.
