/**
 * Fragment created to show a TvShows. This fragment is going to be used in the tablet version.
 *
 * This Fragment uses a Model View View Model implementation to implement all the presentation
 * logic. Review TvShowViewModel to get more info about the implementation.
 *
 * This fragment contains duplicate code that you can see in TvShowDraggableFragment because I want
 * to show two different approaches to work over the Android UI layer with different patterns (MVVM
 * and MVP) and I don't want to mix both fragments in a hierarchy to clarify different
 * implementations.
