+ Dopo di che l'api fa una chiamata a facebook per verificare che il token sia
+ valido e farsi restituire un oggetto che modella il profilo utente associato.
+ Poi questa funziona deve creare un oggetto user profile così come definito da Passport.js.
+ Poi invoca una funziona wrapper che accetta come parametri il nome dell'app, lo user profile e il fb access token e che
+ poi chiama findOrCreateUser, genera api access token e salva api, fb tokens e che ritorna all'utilizzatore l'api
+ access token.
