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.
