ResponseHighlighterInterceptor
This detects when a request is coming from a browser and returns HTML with syntax highlighted XML/JSON instead of just the raw text. In other words, if a user uses a browser to request "http://localhost:8080/openmrs/ws/fhir/Person/d9648997-4e01-406e-b47b-c00cb9b143bb" by typing this address into their URL bar, they will get nice formatted HTML back with a human readable version of the content. This is helpful for testers.
