Demo App stopped working in 0.1.11 release

Previous: https://unpkg.com/@hms-dbmi-bgm/react-workflow-viz@0.1.10/index.html works

Current: https://unpkg.com/@hms-dbmi-bgm/react-workflow-viz@0.1.11/index.html doesn't work (makes requests to localhost:8100)

I think it might have something to do with the build that is published to npm. Need to make sure to do a prod build when push to npm rather than dev build; dev build will use localhost.
