+ * `Strategy` constructor.
+ *
+ * The Google authentication strategy authenticates requests by delegating to
+ * Google using the OAuth protocol.
+ *
+ * Applications must supply a `verify` callback which accepts a `token`,
+ * `tokenSecret` and service-specific `profile`, and then calls the `cb`
+ * callback supplying a `user`, which should be set to `false` if the
+ * credentials are not valid.  If an exception occured, `err` should be set.
+ *
+ * Options:
+ *   - `consumerKey`     identifies client to Google
+ *   - `consumerSecret`  secret used to establish ownership of the consumer key
+ *   - `callbackURL`     URL to which Google will redirect the user after obtaining authorization
+ *
+ * Examples:
+ *
+ *     passport.use(new GoogleStrategy({
+ *         consumerKey: '123-456-789',
+ *         consumerSecret: 'shhh-its-a-secret'
