/**
* A database view needs to report a changeset in the YapDatabaseModifiedNotification.
* The changeset needs to properly indicate any keys that were inserted, deleted, or moved.
*
* If a key is inserted or moved, then the changeset needs to report the original index of the key,
* as it existed at the start of the readwrite transaction.
*
* If a key is deleted or moved, then the changeset needs to report the final index of the key,
* as it exists at the end of the readwrite transaction.
*
* This sounds simple enough in principle.
* But when the transaction may consist of multiple modifications to multiple keys,
* the complexities of the problem begin to add up...
*
* For the test cases below, we will use "ascii art" to diagram the order of changes that occurred in the view.
*
* The views record each change that modifies the view as the modifications occur:
*
* - If a item is inserted, then the insertion index is recorded at the time of the insert.
* - If a key is deleted, then the deletion index is recorded at the time of the delete.
* - If a key is moved, then the change is recorded as 2 separate operations. A delete and then an insert.
*
* The recording of the modifications is quite simple.
* After the transaction is complete, we need to perform post-processing on the changes log in order to:
*
* - deduce the original index value and final index value of modifications
* - consolidate multiple changes to the same key
*
* Notes:
*
* - a MOVE is written as : (originalIndex -> finalIndex)
* - a DELETE is written as : (originalIndex -> ~) because a delete has no final index
* - an INSERT is written as : ( ~ -> finalIndex) because an insert has no original index
