QI Core Value Set and Code System Query Issue

[jenseeman]

Qi core data elements to spreadsheet tooling is missing value set and code systems for race and ethnicity.
These elements are must support under the QI Core patient profile- http:https://hl7.org/fhir/us/qicore/STU4.1.1/StructureDefinition-qicore-patient.html but were not in the last output from the tooling.

The data elements code does not go through the extensions in the elements and add them to the results. If those code systems and value sets are wanted the code needs to be refactored in QICoreElementsToSpreadsheet.java to loop through the extensions. Their format is "Patient.extension:ethnicity".
I wrote this code and would be happy to take this on. If that is desired.
