Cyborgs assimilate natives, and turn them into colonists. One assimilated native clan yields one new cyborg colonist clan.
Native_clans_assimilated = Trunc(Colonist_clans * BorgAssimilationRate / 100) ...at most Native_clans
► Note: PHost versions before 4.1 / 3.5 would have removed Ceil(...) native clans, but only added Trunc(...) clans.
