Website Improvements

[rhl-bthr]

• [ ] Design Rehaul: The current website isn't that great looking. Look at pcapplusplus.github.io OR erpc.io for a better inspiration.
• [ ] On both Github main page and website, the link to the poster's extended abstract should appear upfront. Can appeal modestly to cite our poster if they have benefited from the tool's use. Maybe like this?
• [ ] Current Readme.md shows some table at the top in master, but the same is not visible in develop. So I am sure we can get rid of the same while having all the website related stuff properly organized under docs/.

All have either been fixed, or removed by design.
