==================== Summary ====================

Name: Tools-LM.829

Ancestors: Tools-LM.828

In response to the feedback I received to Tools-LM.828 ( http://forum.world.st/The-Inbox-Tools-LM-828-mcz-td5082873.html ).

I now made the ObjectExplorer only exclude those ObjectExplorerWrappers from the "chase pointers" search that are a submorph of the ActiveWorld.
This is helpful if, for example, one reference to the object in question is held by an ObjectExplorer in another project that you forgot about.

The findDeepSubmorphsIn:that: method should probably be moved into the Morph class, because it is a classic case of feature envy and Morph already contains a findDeepSubmorphThat:ifAbsent: method, which is similar. I just didn't want to mess with one of the core Morphic classes.

I know that the way I find which ObjectExplorerWrappers are visible is not ideal, because it violates the principle of MVC that the model should not know about the implementation specifics of the view. So any feedback and suggestions in that regard would be appreciated.
