// A window controller that handles the preferences window. The bulk of the
// work is handled via Cocoa Bindings and getter/setter methods that wrap
// cross-platform PrefMember objects. When prefs change in the back-end
// (that is, outside of this UI), our observer recieves a notification and can
// tickle the KVO to update the UI so we are always in sync. The bindings are
// specified in the nib file. Preferences are persisted into the back-end
// as they are changed in the UI, and are thus immediately available even while
// the window is still open. When the window closes, a notification is sent
// via the system NotificationCenter. This can be used as a signal to
// release this controller, as it's likely the client wants to enforce there
// only being one (we don't do that internally as it makes it very difficult
// to unit test).
