Implementing the Update User Route

Listing 26.7 implements the updateUser route. This handler finds the user and then sets the values from the req.body.email and req.body.color properties that will come from the update form in the body of the POST request. Then the save() method is called on the User object, and the request is redirected back to the /user route to display the changed results.
