// @description Four visual improvements for Wikipedia (and other wikis): Indents sub-sections to make the layout clearer. Hides the sidebar (toggle by clicking the header). Floats the Table of Contents for access when scrolled. Converts heading underlines to overlines.

/* Changelog
* 5/ 2/2012 - Better (though more fragile) click-to-toggle areas.
* 3/ 1/2012 - Fixed Chrome compatibility so it works! Doh.
