Author: lgiessmann Date: Sun May 2 08:00:41 2010 New Revision: 293

Log: new-datamodel: added helper-functions for creating conditions; modified all delete-<xy> methods, so the parents are now recursively added to the version-history; added to every delete-<xy> function a private one that does the same operation except adding the parent to the version history --> is needed for merging => to avoid mismatches of the versions; adapted changes.lisp except the method "changed-p" to the new datamodel
