This will setup and manage the ad control in your windows phone app page. This wrapper was created to alleviate an intermittent null reference error in multi-page windows phone apps when navigating.
This now has the capability to show your own ads when the ad server fails. Your ad will display for 30 seconds and then try the ad server again. You can also show an app highlight when you open the app. The highlight will show for 10 seconds before attempting the ad server.
Currently the ad control is created at the bottom of the page.
