public interface AuthProvider

This is the main interface representing an authentication provider. First we call the getLoginRedirectURL method to get the URL where the user needs to be redirected. It is the responsibility of the caller to redirect the user to that URL. Once the external provider like Facebook redirects the user back to our application, we call the verifyResponse method and pass along the HttpRequest object that is called upon redirection. If the verifyResponse method returns a non null profile object, we can start calling the other methods to obtain user information, update status or import contacts
