[Tachyon-list] Presentation

I made some minor changes to the ordering of the IR-related slides, added a few details here and there, and created a slide about our HIR. The updated presentation is on google docs (see CASCON2010.odp).

Is this sufficient for my part? Are there other details or diagrams that you guys would like to see me add? I'm figured that since we have access to the source, we can show them as much source code as they like after the presentation.
