from preamble:

"Change Set:		KeysAtValue-nk
Date:			2 August 2002
Author:			Ned Konz

This CS:

* Fixes IdentityDictionary>>keyAtValue: to work right

* Adds keysAtValue: and keysAtIdentityValue: methods to Dictionary that
answer the entire set of keys for a given value. Right now keysAtValue:
raises an exception if none are found; perhaps it should just return an
empty collection.
