// 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 lefiPrivateSubObjects policy corresponds to a deep copy, while the the
// lefiReferencedSubObjects policy corresponds to a shallow copy. Usually an
// initial parent object will be created using lefiPrivateSubObjects. 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 lefiOrphanSubObjects and
// lefiAdoptedSubObjects policies may be used. lefiOrphanSubObjects is
// specified while creating the deep copy, and then lefiAdoptedSubObjects 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.
