check aggregate_area and assign_unknown interaction

[andybeet]

In aggregate_area, the landings and the value can be proportioned from a statistical area (those overlapping multiple EPUS) among EPUS.

This step is completed prior to the assign_unknown step which uses data from this previous step to "fill" in missing variables like AREA, MONTH, NEGEAR (or EPU, MONTH, FLEET) if aggArea or aggGear are turned on.

In this assign_unknow step, if a missing AREA is assigned an AREA value that overlaps two EPUs, are the value and the landings proportioned or is the original landings and value retained? If the latter then we'd be inflating landings and value

[andybeet]

Unsure, but this might be irrelevant. Here's why:

Because the assign_unknowns is the last step in the process we have already aggregated areas and gears. So we are filling in missing values at the aggreate level, based on aggregated data. We should be doing the "data filling" step BEFORE the aggregation step
