toolImportSupplyRatioAggregate This function aggregates bilateral import supply ratios (amount exported from country X divided by domestic supply of country Y) from country to regional level, using two different weights for bilateral spatial dimensions 1.1 and 1.2, where dimension 1.1 is the exporters (no weight, simple summation), while dimension 1.2 are the importers, weighted by domestic supply. THIS ORDER IS IMPORTANT.
