Flash Heatmap

There are some really good Flex based examples out there, but I wanted a pure AS3 option. I found Michael VanDaniker’s examples the most beautiful and easy to understand. So I pulled out what I could to just AS3. I also got some help from sunild. I manually convert pixel to lat / lng coordinates on each map move. There is probably a more efficient way to do this. But I’m going to put to rest AGAIN, tinkering w/ math that is way over my head!
