8af80418ba1ec431c8027fa9668e5678658d3611Allan Foster * This class has the responsibility of creating structural entities. A
8af80418ba1ec431c8027fa9668e5678658d3611Allan Foster * structural entity is an entry which contains other entries (example: people
8af80418ba1ec431c8027fa9668e5678658d3611Allan Foster * container). The information in the DIT (under "StructureTemplates") defines
8af80418ba1ec431c8027fa9668e5678658d3611Allan Foster * the structure . For example, when an Organization is created, it will contain
8af80418ba1ec431c8027fa9668e5678658d3611Allan Foster * a "Groups" container. This class creates the structure of entities as defined
8af80418ba1ec431c8027fa9668e5678658d3611Allan Foster * in the DIT.
