keyAtValue: returns one key of the value specified but if you have more time
the same value the method return one key.
An example:
t:=Dictionary new.
t at: 'toto' put: 4.
t at: 'foo' put: 4.
t keyAtValue:4. -> 'foo'
So we can't recuperate all of the keys. I propose to create the methods
keysAtValue: who return an Array with all the keys for this value.
I'm not in Pharo very long time so I can not say if it can be useful so I am
asking to you the question.
