 * GoogleOpenId allows authentication via Google OpenId.
 * Unlike Google OAuth you do not need to register your application anywhere in order to use Google OpenId.
 *
 * Example application configuration:
 *
 * ~~~
 * 'components' => [
 *     'authClientCollection' => [
 *         'class' => 'yii\authclient\Collection',
 *         'clients' => [
 *             'google' => [
 *                 'class' => 'yii\authclient\clients\GoogleOpenId'
 *             ],
 *         ],
 *     ]
 *     ...
 * ]
