 The default implementation of `func toJSON()` inspects the properties of your type using reflection (see `Company`.) If you need a different mapping, you can provide your own implementation (see `User`.)
 
 Instantiate your struct, then use the `func toJSON()` method to obtain a equivalent form suitable for use with `NSJSONSerialization`:
