* Very Simple RESTful client. This is purely for use in the standalone

*
* <pre><code>
* FHIRSimpleClient fhirClient = new FHIRSimpleClient();
* fhirClient.initialize("http://my.fhir.domain/myServiceRoot");
* </code></pre>
* <p>
* Default Accept and Content-Type headers are application/fhir+xml and application/fhir+json.

* <pre><code>
* setPreferredResourceFormat()
* setPreferredFeedFormat()
* </code></pre>
