aria accessible wcag

I reworked the accessible helper module into an api and a fix and help module. The documentation is below and does an ok job of showing what I am going for. Its more of a proof of concept than an alpha version, but I think it works. I'm definatley looking for feedback. I made an short video also. http://www.youtube.com/watch?v=VZkccMbt7CQ The module is at http://johnbarclay.com/accessible.zip until I get it checked in.
