* Subclass of {@link ModelMap} that implements the {@link Model} interface.

* <p>This is an implementation class exposed to handler methods by Spring MVC, typically via
* a declaration of the {@link org.springframework.ui.Model} interface. There is no need to
* build it within user code; a plain {@link org.springframework.ui.ModelMap} or even a just
* a regular {@link Map} with String keys will be good enough to return a user model.
