// Purpose: Defines a common class for all objects in the world object tree.
//
// Pointers to other objects in the object tree may be stored, but
// they should be set via UpdateDependency rather than directly. This
// insures proper linkage to the other object so that if it moves, is
// removed from the world, or changes in any other way, the dependent
// object is properly notified.
