Added fix to 1) make NSOutlineView faster using Maps and 2) eliminate the need for items to implement NSCopying which is not correct behavior. GJC

2002-04-01 Gregory Casamento <greg_casamento@yahoo.com>
* Source/NSOutlineView.m
Replaced dictionaries w/ NSMapTable. NSDictionary required
items of the NSOutlineView to implement the NSCopying protocol
which is incorrect.
* Headers/gnustep/gui/NSOutlineView.h
Replaced dictionaries in class declaration.
