To be able to easily delete all tags that are not being used as an attribute reference in AF.
I have a total of 150000 tags on my dev server. I only use AF, so if a tag is not in AF I have no use for it. As I am testing things on my dev server, there are lots of things that I try that do not end up being used. I would like a way to easily delete all tags taht I am not using.
