This PR contains the work on implementing some public interfaces that were forgotten during the development of this app and, of course, improves the text of the README file a bit more. To give further details about the work done: - [x] implemented the `Service` protocol in the `Persistence` library and conformed the `PersistenceService` service to it; - [x] implemented the `Service` protocol in the `Remote` library and conformed the `RemoteService` service to it; - [x] implemented the `Application` protocol in the `Core` library and conformed the `UIApplication` class to it; - [x] improved the dependency keys used by the `DependencyService` service to use these protocols instead; - [x] tweaked the text of the README file.
