Updating README.md examples

[iabraham]

If developers want some more (academic) examples to add to the README file, we used Franklin for two courses at Univ. of Illinois (and it has been a very pleasant experience!):

• Signals & Systems for Bioengineering
• Computer Systems & Programming

Also I believe @storopoli 's website now uses Hugo? The linked repo for that entry in README.md errors out.
