Several options

[chandryou]

Hi, @schuemie
I'm currently trying to develope comparative study package by using this skeleton
(https://github.com/OHDSI/StudyProtocolSandbox/tree/master/PneumoniaRiskOfPPI)

I hope some options to be added:

1. delete 'cohort' table
   : Current skeleton delete defined cohort table and create one by the default.
   I think this should be optional. (Actually, I lost all records in cohort table... It doesn't matter for me. But it can be catastrophic for others).

2. Skip 'positive' & / or 'negative' control
   : I want to skip positive and negative control parts in the primitive version of the package, since I don't have negative controls in the first place(I've heard that current ATLAS supports to develop set of negative controls, but I don't know how... ).
   Even if I specified negative controls, the synthesis of positive control doesn't work. And I'm not sure synthesis of positive control is essential for all comparative study.

Thank you for your effort!
