    ##
    # The admin controller is a base controller that should be extended by all controllers
    # for the backend of Zen. This controller will automatically check to see if the 
    # user is logged in and perform several other tasks such as loading all Javascript 
    # and CSS stylesheet along with our helpers and so on.
    #
    # ## Authentication
    #
    # It's important to remember that any controller that extends this one will require 
    # the user to be logged in. The only exception for this is the login method for the 
    # Users controller, mapped to /admin/users/login. If a user isn't logged in he/she 
    # will be redirected to the login page.
