Themis: subgroup: measurement, procedure

There are several updates on the ThemisMeasurements study (and ThemisUnits).

  1. AMIA poster was accepted
  2. Last week we met with Arachne creators and we are improving the code for the study to run in Arachne. (e.g., hint: use extension .ohdsi.sql to make your SQL analysis be recognized as parametized SQL)
  3. We are planning implementation to Achilles Heel (and Achilles Themis?)
  4. SqlRender is struggling with subqueries that have top X logic (issue filed https://github.com/OHDSI/SqlRender/issues/126 )
