Tutorial para AngularFire (AngularJS + Firebase)

Introduccion

En este tutorial haremos uso de AnguarJS y de Firebase (esta combinacion es tambien llamada AngularFire) para implementar un CRUD basico para el ingreso de usuarios. En este tutorial se tiene como requisitos tener instalado git y tener una cuenta en Firebase

AngularJS

Es un framework MVC que esta implementado en Javascript este vive en el lado del cliente (navegador) y dado que usaremos como backend a Firebase que nos da un BD desde el cliente es solo necesario un servidor web para poder enviar HTML, CSS y el Javascript de la aplicacion. Haremos uso de un servidor web usando Node.js desde la consola para ver como va nuestra aplicacion.
