/* I used this web page as a basis: http://www.chovy.com/web-development/self-signed-certs-with-secure-websockets-in-node-js/
   1. I created the key and cert using the instructions.
   2. I created a modified secure websocket server - included below
   3. I created a simplified Scratch extension - included below.
   
   4. I added the cert to firefox using the instructions in the article for Chrome. This worked
   5. I tried to add the cert to chrome by accessing https://0.0.0.0:1234, but this brought me to a search page.
   6. I then created a pkc12 cert and used the settings to add it to chrome, but could not get a wss connection.

   Bottom line - I got Firefox to work, but not chrome
