1 Practitioners Route

When this route receives a request for a list of available practitioners, the route extracts the requested information from the FHIR Server in the form of a FHIR Bundle and splits the data into separate JSON-formatted files, one for each practitioner. The corresponding route component batches the resulting files into a single message, and the route sends the data back through an HTTP response.
