// to register to listen for a notification,
// you simply call push.register and pass an
// topic of interest:

var req = navigator.push.register("topic");


// success callback
req.onsuccess(e) = function() {

  e.target.result.pushEndpoint
  e.target.result.pushRequestID
}

req.onerror() = function(e) {}

// to unregister, you simply call..

req = navigator.push.unregister("topic");
req.onsuccess() = function() {}
req.onerror() = function() {}


// register() will send a request to the
// push server including:

application id making this request
the string token that was passed into the register() call

user auth:  TBD, but most probably headless browserid
