Find the aggregated centroid, or disaggregated centroids, of a set of regions. When the set of regions are "aggregated", all regions will be treated as if they were "combined", or "aggregated" into one region. Only a single pair of longitude/latitude coordinates will be returned for the entire aggregated region. When the set of regions are "disaggregated", the centroid for each region will be calculated "separately", or "disaggregated". A pair of longitude/latitude coordinates will be returned for each region individually.
