The package is essentially an implementation of a PageController
pattern.
Architecture:
* Controller class that examines HTTP requests and manages
form values persistence across requests.
* Page class (subclass of QuickForm) representing a single
page of the form.
* Business logic is contained in subclasses of Action class.
Cool features:
* Includes several default Actions that allow easy building
of multipage forms.
* Includes usage examples for common usage cases (single-page
form, wizard tabbed form).
