 * Hello Data Hook
 *
 * This hook shows how to share data between events within the same hook,
 * e.g. onBeforeAll you could retrieve an oAuth token, store it and re-use it in
 * every onBeforeEach event
 *
 * Another possibility is to even share data across all other hooks, by putting
 * the data onto the hookhandler.
