Streamline PQ and TQ distirbution
In interventions where PQ and/or TQ id given, there seems to be some redundancies in propagating individual-based flags (PQ_treat, TQ_treat...) to vectorized population-level data. For instance, the whole block found in commit d51e87db at lines 899-905 could be simplified into something like:
POP.people[n].PQ_treat = PQ_treat;
To be discussed with @mwhite before making changes here, because this could be to keep the code consistent across interventions.
Again, just keeping this issue opened for now as a reference for future code refactoring if needed.
