Set SCT Aggregation Summary Functions -- "RiverWare Default"
Phil Weinstein, CADSWES, edit 5-11-2011

The initial default setting (which can be set by clicking the "Restore
RiverWare Default" button) is defined in code, in this module:

------------------------------
QtSCT/SctSumFuncAssignSpec.cpp
------------------------------

// The intial default case, applied to Slots not matching any of the Unit 
// Type or Slot Name (Part) filters in the sequence of filter rows.
//
static const SctSumFunc DEFAULT_SUMFUNC (SCT_SUMFUNC_LAST);

In method:

  // static
  const SctSumFuncAssignSpec& SctSumFuncAssignSpec::factoryValueRef()
  {
     // Returns a const reference to a static SctSumFuncAssignSpec
     // instance having the "Factory" default settings.

     ... ... ...

     Item lastItem (true); // last item
     lastItem.setSumFuncSpec (SctSumFuncSpec (DEFAULT_SUMFUNC));

     QList<Item> itemList;
     itemList << Item (FLOW,   SCT_SUMFUNC_SUM)  // 1
              << Item (VOLUME, SCT_SUMFUNC_AVE)  // 2
              << lastItem;                       // 3

     ... ... ...
  }

---------------------
SctSumFuncSpec Values
---------------------

The Summary Functions are defined file: SctSumFuncSpec.hpp.
Ordinal ("Nth") values are constructed with two paremeters:

  SctSumFuncSpec (SCT_SUMFUNC_NTH, n);
  ... where 'n' is an int.

typedef enum {
  SCT_SUMFUNC_UND = 0,
  SCT_SUMFUNC_FIRST,
  SCT_SUMFUNC_NTH,
  SCT_SUMFUNC_LAST,
  SCT_SUMFUNC_SUM,
  SCT_SUMFUNC_AVE,  // mean
  SCT_SUMFUNC_MED,  // median
  SCT_SUMFUNC_MIN,
  SCT_SUMFUNC_MAX
} SctSumFunc;
