ResyncFromDatabase
------------------
This sample shows how to synchronize rows with the current state of the database.

It has two methods, synchronizing all rows and synchronizing a single row.

Synchronizing one row, changes made to that row by other users will appear in the row,
unless the same field was changed by the current user.

Synchronizing all rows, changes made by other users will become visible.
Changes made by the current user are preserved. Rows added by other users will appear, rows
deleted by other users will disappear (unless they were changed by the current user), rows
modified by other users will show new field values (except fields changed by the current user,
all changes made by the current user are preserved).
