code: private IBaseResource filterNestedBundle(RequestDetails theRequestDetails, IBaseResource theResource) {
  		IParser p = getContext().newJsonParser();
  		RestfulServerUtils.configureResponseParser(theRequestDetails, p);
  		return p.parseResource(theResource.getClass(), p.encodeResourceToString(theResource));
  	}
docs: This method is called for nested bundles (e.g. if we received a transaction with an entry that
  was a GET search, this method is called on the bundle for the search result, that will be placed in the
  outer bundle). This method applies the _summary and _content parameters to the output of
  that bundle.

  TODO: This isn't the most efficient way of doing this.. hopefully we can come up with something better in the future.
