Bing Maps layer issue

[rbrundritt]

This implementation does not access the Bing Maps tiles in away that aligns with the terms of use of the Bing Maps platform. Your application must call the Bing Maps imagery metadata service each time it loads to get the latest map tile URL's. This is used to track usage for billing and also ensures your app has the latest map tile URLs as they do change from time to time and your current code will break. Here is documentation on how to implement this in such a way that aligns with the Bing Maps terms of use: https://msdn.microsoft.com/en-us/library/mt823633.aspx
