 *         Adapter created to manage the Renderers. This is the main class of this library.
 *         The main objective of this class is to avoid creating new adapters for each type of data
 *         we want to show in our RecyclerViews. Also, this adapter allows to display different
 *         elements with different data that exexute different actions.
