public interface Place

Important: For simplicity, places do not participate in dependency injection and can be created with new.

A place represents a particular 'bookmark' or location inside the application. A place is stateful - it may represent a location with it's current settings, such as a particular ID value, or other unique indicators that will allow a user to track back to that location later, either via a browser bookmark, or by clicking the 'back' button.
