Kh redesign

@boonrs adding my redesign changes. Everything is in redesign.html and redesign.css. Quite a bit has changed ...

- Incorporated new design
- Created new classes (infographic, info-group, info-title, etc etc)
- Used a flex-box model for proper alignment (these are the supported browsers: http://caniuse.com/flexbox)
- Added responsiveness
- Removed Nav (isn't really necessary for this amount of data, adds unnecessary UI complexity)

Next steps: 
- create a visual to explain how the model works
- template it!
- consider removing bootstrap entirely (I think there's only 1 bootstrap class I currently use)
- Add options to share
I miss the sidebar in the new design. I liked being able to jump to sections.
