 * An demo implementation of a Google login flow.
 *
 * To run this you'll need to install `google-auth-library` from npm.
 *
 * Then add this plugin to the dev config.
 *
 * The "storefront" is a simple html file which is served on http://localhost:3000/google-login,
 * but to get it to work with the Google login button you'll need to resolve it to some
 * public-looking url such as `http://google-login-test.com` by modifying your OS
 * hosts file.
