Implementing the Delete User Route

The code in Listing 26.8 implements the deleteUser route. This route finds the user in the MongoDB database and then calls the remove() method on the User object to remove the user from the database. Also notice that req.session.destroy() is called to remove the session because the user no longer exists.
