OAuth Recap

saving oauth logic for later when i get confused on what i wrote:

• User clicks on Sign In With Google Button.
• oauth-start route triggered on backend, which fetches auth url from Google Servers. Then redirects user to this auth-url.
• Once user finishes auth, Google fires callback to oauth-callback with auth code
• API calls for handshake with Google servers to exchange code for credentials and user info
• Obtain credentials, cache in Mongo for later.
• Redirect to /oauth-complete?email=
• React catches this, loads OAuth Component, gets user email and passes internally to /dashboard
