How to set up user authentication for a Chrome Extension using the Chrome Identity API

1. Create a private key file, from which you can create the manifest key and Application ID, as detailed here: https://stackoverflow.com/questions/23873623/obtaining-chrome-extension-id-for-development
2. Add the manifest key to "key" in manifest.json
3. Create a new project in Google Developer Console https://console.developers.google.com/project
4. Go to "APIs & auth > Credentials" and create new client id for a Chrome Application using the Application ID generated in step 3.
5. Copy the Client ID to oauth2.client_id in the manifest.json
