study output advice

[Sigfried]

I don't know the best way(s) to have a study intended for multi-site execution generate output. createTable1 isn't in a great format for aggregating across sites. I wrote some code that generates plain lists of aggregated covariates and stores them in csv files. Maybe that's good?

My question is also how to balance benefit for the site and benefit for the study. Some studies provide nice local output report. Some best practices for that would be good.
