Containers

Context: HL Kit … Basic Concepts and Terminology … Structural Building Blocks 

The term "container" is used to generically refer to both actors and gizmos, since both actors and gizmos contain an assortment of picks. Actors involve a great deal more behaviors than gizmos, and gizmos are not a proper subset of actors. However, whenever something applies equally to both actors and gizmos, it will be described as applying to containers.
