This PR allows the mock data to be sent from simoc-sam to simoc-web. It resolves the following issue.

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:8081/socket.io/?EIO=4&transport=polling&t=NslouJ3. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing)

I merged the PR, even though this only fixes the problem while testing on localhost. We will probably need to come back to this once we deploy this in the real world.
