Defines the core, session-persistant object used to run a Tapestry
application for a single client (each client will have its own instance of the engine).
The engine exists to provide core services to the pages and components
that make up the application. The engine is a delegate to the
ApplicationServlet via the service(RequestContext) method.
Engine instances are persisted in the HttpSession and are serializable.
