Gh pages audit

This audit covers the overview and usage section for each component. The examples sections will come next (there are plans for gist driven examples with jsfiddle type tinker-boxes). Lots of work to be done yet here, but, I think this is a good stopping point for the "first pass".
Any reason to remove the second one here?  It doesn't take up any additional space... though I will say it isn't immediately obvious what it does until you scroll all the way down.
