A custom address picker (stunnware)

I have written address look up programs before for CRM; however, STUNNWARE has a clever way of using the quote's Address look up to do the same thing. It is a great idea, but I would probably put the code in the onload event as a function instead of the ISV.Config file. Putting a lot of JavaScript in the config file will make it difficult to maintain. His article can be found here.
