Get the initial client/server integration set up

Make sure we account for CORS (https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS).

Ideally, we should handle app-wide configurations in one place so as to simplify the various requests that will be sent to the API throughout the application.

This will require changes to both client and server.
