This PR contains the work done to define the `Coordinator` and the `Router` public protocols, and also implemented a few concrete router implementations tailored for the **UIKit** framework. To provide further details about the work done: - [x] define a new, dedicated `Coordinator` target in the `Package` file; - [x] define the `Coordinator` and the `Router` public protocols used to implement the coordinator pattern; - [x] implemented some **UIKit** specific routers to use on the **iOS** platform: `ModalNavigationRouter`, `PushNavigationRouter` and the `WindowRouter` concrete routers.
