Miroslav Bajtoš 62d2b0bf0d change: skip cp lookup on no change ... Modify `Change.rectify` to look up the current checkpoint only when there was actually some change made. This should improve the performance of `rectifyAll` when called from a regular timer and there were no changes made since the last call. Before this commit, `rectifyAll` would perform N calls of `Checkpoint.current` where N is the number of model instances. With this commit in place, no call is made.		2015-12-08 17:54:26 +01:00
