title: push notifications on all 3 platforms (android,ios,windows phone)
body: <p>I'm planning a cross-platform app. Is it possible to implement push notifications on all 3 of them (iphone, android, windowsphone) using only one API/module?
   Is there any other alternative? What needs to be done server-side? Please point me in the right direction. (Documentation, example code if exists)
  Thanks in advance.</p>
