Using the types generated from #4, implement each screen: - `ListOnly`: `AdaptiveLayoutsListScreen` only - `DetailOnly`: `AdaptiveLayoutsDetailScreen` only - `ListOneThirdAndDetailTwoThirds`: `AdaptiveLayoutsListScreen` (33%) and `AdaptiveLayoutsDetailScreen` (rest), left to right - `ListHalfAndDetailHalf`: `AdaptiveLayoutsListScreen` (50%) and `AdaptiveLayoutsDetailScreen` (rest), left to right - `ListDetailStacked`: `AdaptiveLayoutsListScreen` (50%) and `AdaptiveLayoutsDetailScreen` (rest), top to bottom `DetailOnly` will not be testable since there is no shared data stream to communicate when a number has been selected. That will be implemented in #6.
