title: Rich push in Urbanairship in android
body: <p>I am implementing Push Notification for Android in my project. I am implementing urbanairship GCM push Notification.While i gone through the urbanairship site, i camr to notice that under the messages tab, there is an option for "TEST RICH PUSH". I have already done tested simple push by sending push messages from "TEST PUSH" under the tab messsages. Now my question is in "TEST RICH PUSH", there are two new fields "USER" and "ALIAS". Is Rich push is used for sending push notification only to a particualar user currently using an App. or it has got any other purpose. Also please let me know how to enable "RICH PUSH" in their new website.(Earlier it is staright forward. Now i looked in their whole website, But i couldn't find a clue). Any help in this is highly appreciated.`</p>
  
  <p>Thanks InAdvance</p>
