Change tracking

Change documents: a change document object covers the tables of a business object, fields are logged where their data element has change document logging switched on, and function modules such as CHANGEDOCUMENT_READ_HEADERS and CHANGEDOCUMENT_READ_POSITIONS read the history back with old and new values.

Not covered: At changes: in the sample checked only changes are recorded and not initial values, so a record's history starts at its first edit. An OData V4 Fiori elements app does not use the reuse display library, and the sample reads the change documents through a custom entity instead.
