Classes

This class is meant to act as an “abstract” base class, providing a simple Dictionary datastore that is stored in the UserDefaults in the Application Bundle. It is designed to be reliable, and extremely simple to use. The stored Dictionary would be a String-keyed Dictionary of Any (flexible types). It s up to subclasses to specialize the typeless data. THIS IS NOT EFFICIENT OR ROBUST! It is meant as a simple “bucket” for things like application preferences. It is not an industrial data storage solution. You have been warned. Subclasses could declare their accessors as KVO-style, thus, providing a direct way to influence persistent state. You can also directly observe the .values property. It will change when ANY pref is changed (so might not be suitable for “pick and choose” observation).

This class extends the prefs class to provide persistent prefs storage. This is used across all test harnesses.

The navigation controller is used to maintain the driver instance.

I know that I should define another class to do that, to be buzzword-compliant, but otherwise, this class would be empty, and there’s no sense wasting the namespace.

This is a common base class for our navigation-managed view controllers.
