# A RangedLotCategory is an estimate used to assert that a CollectoinObject contains somewhere between a minimum and maximum
# number of individuals, as asserted by a curator of that CollectionObject.  When a RangedLotCategory is assigned to
# a CollectionObject then no CollectionObject#total can be provided.
