fhirbuffer is a gRPC service to export data from Fhirbase. The one thing we want it to do well is talk gRPC. So a downstream process isn't aware of the database, SQL, and ultimately even Go.

For a prototype of the end-to-end flow, see fhirping app hosted on Glitch. Read the summary blog post.

1. Install Fhirbase (see their Get Started steps)
2. Git clone repo
3. Docker build
