RequestConsumer (ipf-commons-ihe-fhir 3.1.1 API)

```
public interface RequestConsumer
```
Consumer interface of FHIR requests. Plain providers or resource providers forward the request data received to an instance of this interface to be processed. This decouples request reception from request handling, so you can e.g. use the IHE resource providers outside of Apache Camel.
