Redux está implementado. Creamos el store en App.js, nos connectamos a redux con connect en Home_page.js. Tenemos una sugeunda ruta de navegación Home a la que se accesa despues de que el usario está loggedIn. Esto está en el return de App.js. El store de redux es un provider de estado común a los componentes y envuelve el container de navegación.
