gapi.auth.signOut() signs the current user out of your app.
A new status field indicates whether users are signed in to Google and/or your website, and a new method field describes how the sign-in occurred.
You can now specify sign-in parameters once in <meta> tags, versus passing them multiple times to multiple page elements. These page-level configuration parameters simplify your integration of Google+ Sign-In and interactive posts.
