// Returns a |GPPDeepLink| for your app to handle, or |nil| if not found. The
// deep-link ID can be obtained from |GPPDeepLink|. It is stored when a user
// clicks a link to your app from a Google+ post, but hasn't yet installed your
// app. The user will be redirected to the App Store to install your app. This
// method should be called on or near your app launch to take the user to
// deep-link ID within your app.

// This method should be called from your |UIApplicationDelegate|'s
// |application:openURL:sourceApplication:annotation|. Returns
// |GooglePlusDeepLink| if |GooglePlusDeepLink| handled this URL, |nil|
// otherwise.
