struct ContactItemSyncAnchor

A snapshot point into enumerating changed contact items. You can break an enumeration of changes into batches with multiple anchors to reduce the memory constraints on the system. During enumeration, you may update the `generationMarker` and `offset` to reflect progress enumerating the changes as they occurred, possibly across mutiple database generations and how many changes occurred within each database generation.
