Report concept set presences that are 0

[alondhe]

When using addPresence, we currently lose line items for concept sets that have no presence during the time window.

For table reporting, it's useful to keep these in with N = 0 and Percent = 0.

I will try to fix this but this maybe an artifact of summarizing in SQL. If there is no count for a concept set and I do a GROUP BY, it won't use an item that is not present.

Can add a post-processing step to add a placeholder for concept set with no presence or are below a minimum reportable value (say <5). Agree something should be done for sake of completeness

Agreed, doesn't need to be during processing. But I think it'd be great if in the add(Domain)Presence functions, we keep a parameter like 'reportZero' and then in the finished categorical result, we get those items.
