All audits made during the block called will be recorded as made by
user
. This method is hopefully threadsafe, making it ideal for
background operations that require audit information.

Return all audits older than the current one.

Returns a hash of the changed attributes with the new values

Return an instance of what the object looked like at this revision. If the object has been destroyed, this will be a new record.
