Lyubov agreed to the idea of a JSON interpreter, to help caDSR and others to move off of RMI.  She wants it to be generally useful, not tailored only to caDSR.

• CTRP - what is it NCI Clinical Trials Reporting Program (CTRP) User Guides
• Source code for the class that calls lexevs64
• Their diagram of key return values
• My attempt at a mapping to CTS2
• Sample query
