docs: `Strategy` constructor.
  
  The Google authentication strategy authenticates requests by delegating to
  Google using the OAuth 2.0 protocol.
  
  Applications must supply a `verify` callback which accepts an `accessToken`,
  `refreshToken` and service-specific `profile`, and then calls the `done`
  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:
  - `clientId`      	your Google application's client id
  - `clientSecret`  	your Google application's client secret
  - `callbackURL`   	URL to which Google will redirect the user after granting authorizationin your Google Application
  
  Examples:
  
  passport.use(new GoogleDriveStrategy({
  clientID: '123-456-789',
  clientSecret: 'shhh-its-a-secret'
  callbackURL: 'https://www.example.net/auth/google-drive/callback'
  },
  function(accessToken, refreshToken, profile, done) {
  User.findOrCreate(..., function (err, user) {
  done(err, user);
  });
  }
  ));
