Right now, Probe's rely on a
          special method, getInstanceName, that has
          to be implemented in any probe-able object in order to get
          anything other than the class name of that object into the
          object designation widget.  However, a more general
          capability has been added to defobj to
          give a meaningful name to any object.
          Probes will be changed to take
          advantage of this new capability.
        
In the ActivityControl the
          frequency of the message updateStateVar
          is very high.  It is sent at least once every cycle and
          every time a message is sent to the
          ActivityControl.  This is
          unsatisfactory.  Some of these messages can be pruned out of
          the object.
The probeMap designed for use with an
          ActivityControl was chosen fairly
          arbitrarily.  Right now, it serves as a default for the
          class.  A user can override it by designing a new one and
          inserting it into the probeLibrary.
          
Errors specific to objects in the objectbase library need to be gathered and initialized like those in the defobj library.
