Improve `bin/utils/redcap_records.py` - now works with json/xml
Add `choices` to indicate valid `-t` option for running redcap_records.py
Usage now displays: [-t {json,csv,xml}]
When there is an error we get:
   redcap_records.py: error: argument -t/--type: invalid choice: 'csv2' (choose from 'json', 'csv', 'xml')

Add clinical-commit-to-loinc.xml helper scripts

- generate_cctl.py generates the XML from a CSV
- cctl_to_csv.py writes out a CSV from an XML

Careful, the CSV from cctl_to_csv.py cannot be read in by
generate_cctl.py without modification.
Add unit test `TestRediEmail.py` to verify changed code for Issue #47
