title: subscribing to an event bus
body: <p>I am trying to use guava for subscribing to EventBus. Trying to look at the site doc but unable to see any example where it shows how to do it.</p>
  
  <p>Anyone tried this before??</p>
  
  <pre><code>private final EventBus eventBus = new EventBus();
  eventBus.post(eventId); // where eventId is a string.
  </code></pre>
  
  <p>This is being in one of the jars. Now I need to subscribe to this eventbus and check if there are any new eventId's posted. How can I do that?</p>
  
  <p>Any help is appreciated. </p>
  
  <p>Thanks!!</p>
