Programattically replace Placeholder with Ads

[rakeshgirase]

Nativescript provides placeholder which can be replaced with any view at runtime. It would be great if a placeholder can be replaced with AdView using Admob. An example is given at https://www.nativescript.org/blog/monetize-your-nativescript-apps-with-admob-(part-1---ios) and https://www.nativescript.org/blog/monetize-your-nativescript-apps-with-admob-(part-2---android).
