- * Map the given param placeholder `name`(s) to the given callback.

- * Parameter mapping is used to provide pre-conditions to routes
- * which use normalized placeholders. For example a _:user_id_ parameter
- * could automatically load a user's information from the database without
- * any additional code,
- *
- * The callback uses the same signature as middleware, the only difference
- * being that the value of the placeholder is passed, in this case the _id_
- * of the user. Once the `next()` function is invoked, just like middleware
- * it will continue on to execute the route, or subsequent parameter functions.
- *
- * Just like in middleware, you must either respond to the request or call next
- * to avoid stalling the request.
