Generate html directly

[nfischer]

Generating markdown and converting it to html works, but is very limiting. I think we can achieve much nicer results if we programmatically build a DOM and then write it out to a file. This should be easy to achieve using something like xmlbuilder. If we add in css files, then we can have complete control over styling, which is good.

I thought about doing this, but I feel like it would be much more complicated. I'm not sure if it's worth it.
