update

Not sure if this is how to update the files, but whatever.
I made changes to all pages with regard to css and the side bar (which now features callbacks) Some links were added as well. Some files were added/removed (images and a test text file for ajax which still isn't completed) and i think that's it for now. Still working on ajax. All pages were validated. I think we have all the required features under html, js and css. Kinda want to embed a couple videos on page 3 and/or the methods page.
