/**
* Annotates the field should be 'required' in the UI. For example, should be displayed with a star
* after it and, depending on the target UI platform, have 'required' validators attached to it.
*
* Note: Metawidget is designed to use existing annotations as much as possible. Clients
* should use something like javax.persistence.Column(nullable = false) or
* org.hibernate.validator.NotNull in preference to UiRequired.
