[Cuis-dev] Rename class not logging to user changes

Maybe they should be recorded both ways: as ClassRename and as sequence 
{ClassCreation. NewMethods. UpdateClassReferences. OldClassRemoval}. 
There are some reasons for wanting the sequence. One is to be able to 
re-apply changes, or not require to be in exactly the same state as when 
the change was created.

If both ways are included, then the user of the file can decide what 
s(he) prefers.
