[dgghun]

Remove the following directories/files in the develop branch:

• [x] /public
• [x] /video_chat.html
• [x] /js/app.js
• [x] /now.sh
• [x] check that app still works

@dgghun Deleted files. App runs locally. Need to push files to server to check remote. Creating pull request for you to test.
