Frequent word count superscript : Is double div causing slowdown? #82

Granted, we'll be adding lots more crap to the transcript and we'll definitely look into culling the offscreen paragraphs—part of the slowdown might be coming from the double-div for the superscripts.

Is there a way to make those superscripts a single span? And have them either added as a child of the word span or actually inserted into the word span flow?

PS Animation of these isn't high priority. Since they're so tiny, they can just show up.

I think I found the main source of scrolling performance-- I was finding the elements in view on the page by using $(el).offset() which apparently is really slow. Now I'm caching each paragraph's top and bottom positions in 'data-top' and 'data-bottom' attributes. This makes things much snappier.

Wowsers—much smoover. Thanks.
