D'oh, I see it now. For TextEditor>>browseClassFromIt the answer is no we
do not need to go via SystemNavigation. And there are four other senders of
SystemNavigation>>spawnHierarchyForClass:selector: that could also be
changed to refer directly to ToolSet.

On the other hand, knowing about the hierarchy for a class seems to be more
naturally a responsibility of a SystemNavigation than of a ToolSet, especially
since the responsibilities of class ToolSet are rather vague (it seems
to be just an assortment of class side utility methods). So even though
#spawnHierarcyForClass:selector: is using ToolSet, the method seems well
placed in SystemNavigation.

I'd say leave it alone.
