Phil [10-2-2013]: Typical iteration over controllers for the purpose 
of calling SimObj::getSlotsInUse (cwDlist<Slot*>& slotsInUse, RunType).

//-----------------------------------------------------------------------------
//-----------------------------------------------------------------------------

   // Show slots for all of these controllers
   RunType allControllers[] = { RT_SIMULATION, RT_OPT,
                                RT_RULEBASED, RT_ACCOUNTING,
                                RT_SIM_ACCOUNTING, RT_RULE_ACCOUNTING };

   const int ctrlCnt (sizeof(allControllers) / sizeof(allControllers[0]));

   for (int inx = 0; inx < ctrlCnt; ++inx)
   {
      cwDlist<Slot*> currSlotList;
      const RunType ctlType = allControllers [inx];
      refObj->getSlotsInUse (currSlotList, ctlType);
      ...
   }

//-----------------------------------------------------------------------------
//-----------------------------------------------------------------------------

Note that the above doesn't include RT_MRM. (That may be OK, but how does
a programmer know that?).

  typedef enum {
      RT_UNKNOWN=-1,
      RT_SIMULATION=0,
      RT_OLD_OPT=1,
      RT_RULEBASED=2,
      RT_MRM=3,
      RT_ACCOUNTING=4,
      RT_SIM_ACCOUNTING=5,
      RT_RULE_ACCOUNTING=6,
      RT_OPT=7
  } RunType;
