// Notes: There are three different way of extracting the differences
// between a given storage and another point of reference
// (another storage, a version id. or a time stamp). In the
// first case there is no temporal significance to the differences
// extracted, i.e., it is the difference in the snapshots at
// that instant of time. For the second and third cases there
// is a temporal significance attached to the differences. These
// also require some form of history to be associated with the
// storage.
