The Arguments protocol has moved
          from the objectbase library to the
          defobj library.  If you were subclassing
          from the Arguments class you will now
          need to subclass from Arguments_c and
          import the defobj.h header file.
The ListShuffler class has been
          moved from simtools to
          collections.  You must now import
          collections.h.  Alternatively you can
          use the new [beginPermuted: aZone]
          index creation method on a collection from the           Collection protocol in place
          of the ListShuffler protocol.
        
The -setLabels:: and
        -setColors:: methods in the Histogram
        protocol now each must be given a new count:
        (unsigned)labelCount and count:
        (unsigned)colorCount argument, respectively.  So,
        for example, the code formerly in
        MarketObserverSwarm.m in the
        market application was:
[useHisto setLabels: pred]; [useHisto setColors: predictorColors];
is now changed to:
[useHisto setLabels: pred count: numPredictorsToShow]; [useHisto setColors: predictorColors count: numPredictorsToShow];
