The code for as-detector is pretty hard to read. It seems much of the design was because effort was made to avoid depending on ASTools. The AS-detector has depended on ASTools for a while, though, so it seems like a good time to really clean that code and help make the number of problems smaller wherever possible.

I'm attaching a patch which makes use of newer APIs in astools which helped remove a lot of the code in the ASHandler. I also separated out the driver stuff into its own class to keep it cleaner.
