 'facebook' => [

    return view('facebookAuth');

});



Route::get('auth/facebook', 'Auth\RegisterController@redirectToFacebook');

Route::get('auth/facebook/callback', 'Auth\RegisterController@handleFacebookCallback');

     */
    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => 'required|max:255',
            'email' => 'required|email|max:255|unique:users',
            'password' => 'required|min:6|confirmed',
        ]);
    }

    /**

     * @return User
     */
    protected function create(array $data)
