/* The memory policy controls how an object which refers to or is composed of
 * other objects manages those sub-objects, particularly when the parent
 * object is copied or deleted.  The policy is specified as an argument to the
 * constructor or initializer, and it is stored with the parent object.
 *
 * The memory policy is a generalization of the common distinction between
 * deep and shallow copies.  When a shallow copy of a parent object is made,
 * the copy maintains pointers to the original sub-objects, and the original
 * parent remains responsible for deleting those sub-objects.  When a deep
 * copy of a parent object is made, the copy maintains pointers to new copies
 * of each of the sub-objects, and the copy is responsible for deleting the
 * new sub-objects.
 *
 * The defiPrivateSubObjects policy corresponds to a deep copy, while the the
 * defiReferencedSubObjects policy corresponds to a shallow copy.  Usually an
 * initial parent object will be created using defiPrivateSubObjects.  When a
 * copy is made of that parent object, the copy may either maintain its own
 * private versions of each sub-object, or it may refer to the original
 * sub-objects.
 *
 * In certain cases, it is useful to create a deep copy of a parent object,
 * even though the new parent object shouldn't be responsible for the new
 * sub-objects.  In this case, the defiOrphanSubObjects and
 * defiAdoptedSubObjects policies may be used.  defiOrphanSubObjects is
 * specified while creating the deep copy, and then defiAdoptedSubObjects is
 * specified while creating another parent which will take on the
 * responsibility for the orphans.
 *
 * An object's memory policy affects only the sub-objects which it directly
 * controls.  Those sub-objects themselves may have the same memory policy as
 * their parents, or they may have a different memory policy.  When a copy is
 * made of a child sub-object, the memory policy of the child controls
 * whether deep or shallow copies are made of the grandchildren.
