==================== Summary ====================
Name: SystemEditor-mtf.143 Author: mtf Time: 25 October 2008, 10:02:56 pm UUID: c6fe8815-84e4-4c81-a55c-6f5a70aa8253 Ancestors: SystemEditor-mtf.142
an experimental InstanceMigrator refactor that should be able to find all instances of any number of classes in constant, rather than linear, time, hopefully resulting in a nice speedup in the average case. It is not yet used, so this change is harmless
