Sample projects for Flock of Swifts meetup on 9-July-2022

Demonstration of the new Navigation API's in iOS16. We dicussed:

• Using an actor for the service layer
• NavigationSplitView
• NavigationStack
• NavigationPath
• Deep linking and deserialization of NavigationPath to JSON
• State restoration with @SceneStorage (not the save interval is infrequent, use @AppStorage if you want to see it work more reliably)
