One parent-to-child edge among areas of a release, as
published_area_relations and its release-scoped base release_relations
project it.
Read-only. intersection_area_m2, parent_coverage and child_coverage
carry a value only for a measured relation; all three are null for one
asserted from source data. parent_coverage and child_coverage are ratios
from 0 to 1, not the percentages GeoGenius.AreaMatch reports.
