removed anything that had to deal with configuring SSL/TLS
updated Author for intro to sets and functions tutorial. Replaced github username with real name.
fixed bug for navbar dropdown fix when user clicks away from the dropdowns
Reason
We want to remove everything for setting up SSL because we are using nginx as a reverse proxy in production so we only have to configure nginx to use SSL to get it working. We can leave the express server running on http in the background.
