Hi,

I have an application I'm trying to angularize. In this app part of the 
interface is in an iframe. This is so that the stylesheet for the content 
in the iframe is isolated from the styles of the rest of the interface. I'm 
trying to bind the data from the parent document in the iframe however I'm 
running into some problems with this. Since the content in the iframe is 
not part of the parent document even adding the ng-app directive to the 
<html>-tag won't affect content in the iframe (it won't be bootstrapped by 
angular). If I manually bootstrap the content of the iframe 
(window.parent.angular.bootstrap(document.documentElement, ['myApp'])) will 
create a separate application which means I can't just use services to 
share data. I've sort of hacked around this issue by having the service 
factory check for a cached value
 on $window and $window.parent and return that if it exists. That leaves me 
with one issue: the digest cycle. Because I now have essentially two 
angular apps sharing the same variable for "communication" making a change 
in one won't trigger the digest cycle in the other, see my plnkr.

I'm hoping there is a better, more proper way to solve this, but if there 
isn't, what would be the best strategy to trigger the digest cycle from the 
other app (without each digest cycle continually triggering eachother)
