jQuery UI: Simplified Accordion

Maybe you're using the jQuery UI accordion widget, and you don't necessarily like the way it looks by default. Maybe this isn't a tunable theme setting that the theme roller can fix either. I know I've been faced with this situation before, I just want the widget simplified, right down to the bare essentials. There is a quick hack we can use to achieve this with the accordion if all you're looking for is a visual simplification.
