-- The fauna feature contains 2 herds of creatures (herbivores and carnivores) that wander between 2 life zones (sleep zone and 
-- food zone).There are 2 differents kinds of components in this feature: fauna system and creature.
-- The fauna system component is some kind of manager for the feature. It creates the creatures and their life zones, and then
-- store them in its components table, so that their createChostComponents call and translation are automatically done by 
-- the translator.
-- The created life zones are affected to each of the creature components. But the properties panel of the creature components allows
-- the DM to choose other zones in the scenario through RefId picking.
