Interesting, but be warned that this CS will break Connectors, as it 
conflicts with a change to Morph (the one change to the base image 
made by Connectors). (Morph>>addedOrRemovedSubmorph:). The change 
that Connectors makes could be used by this CS, though.

Even after fixing that conflict, it doesn't work too well with 
Connectors. I suspect that some morphs will have to return false to 
beAdjacent (like the connectors themselves, and the highlight morphs, 
which are right now not special Morphs).

Enclosed are two change sets.

AdjacencyLayoutAdditions-nk.1.cs.gz adds #beAdjacent to a number of 
classes so that AdjacencyLayout-ajh plays more nicely with Squeak if 
you do:
World layoutPolicy: AdjacencyLayout new
like I did to test it out.

AdjacencyLayoutConnectors-nk.1.cs.gz makes AdjacencyLayout-ajh work 
better with Connectors. Don't file this one in unless you have *both* 
AdjacencyLayout-ajh and Connectors loaded in your image.
