RiverWare 5.1 (Development) Enhancement -- January 22, 2009

New SeriesSlot and Supply RootFilter (for RootSelections and GUS):
 Slots having a timestep with the specified RPL PRIORITY number.

  +--------------------------+
  |  [X][+] "Has Priority"   | 
  |  [ Integer Spinner ]     |
  +--------------------------+

In GUS, this is the first implementation of a GUS_FILTER_TYPE_INTEGER
filter control (using an Integer QSpinBox).  The integer value is
unconstrained.

New:
  RootFilter::FilterType:  FILTER_SLOT_HAS_PRIORITY
  RootFilter::FilterType:  FILTER_SUPPLY_HAS_PRIORITY
  GusFilterControlType:    GUS_FILTER_TYPE_INTEGER

These are "expensive" filters, added to RootSelections only if calling
this method with a TRUE parameter value (expensiveOnesTo):

 void RootSelection::addAllAvailableFilters (bool expensiveOnesToo = false);
 ... OR by calling: addFilter (RootFilter::FilterType);

------------------
Sim/RootFilter.hpp
Sim/RootFilter.cpp
------------------

  typedef enum
  { ... ... ...
    FILTER_SLOT_HAS_PRIORITY,     <<< ADDED
    FILTER_SUPPLY_HAS_PRIORITY    <<< ADDED
  } FilterType;

-----------------------
Sim/RootFilter.Slot.cpp
Sim/RootFilter.Slot.hpp
-----------------------

  NEW:
    class RootFilter_SeriesHasPriority  : public RootFilter;

-----------------------------
Sim/SelectionPart.Slot.cpp
Sim/SelectionPart.Supply.cpp
-----------------------------

void SelectionPart_Slot::addAllAvailableFilters (bool expensiveOnesToo)
{
   ... ... ...
   if (expensiveOnesToo)
   {
      addFilter (RootFilter::FILTER_SLOT_HAS_FLAG);
      addFilter (RootFilter::FILTER_SLOT_HAS_PRIORITY);  // <<< NEW
   }
}

... and similar addition to class SelectionPart_Supply.

--------------------
Sim/SlotGUIUtils.hpp
Sim/SlotGUIUtils.cpp
--------------------

New public predicate function:
  bool SlotGUIUtils::hasPriority (const SeriesSlot*, 
                                  const int refPriority,
                                  Date_Time* firstFoundDtRet=NULL);

Q3GUI/GusTypes.hpp
Q3GUI/GusFilter.cpp
-------------------

typedef enum {
  GUS_FILTER_TYPE_UND = 0,
  GUS_FILTER_TYPE_STRING,
  GUS_FILTER_TYPE_SELECT,
  GUS_FILTER_TYPE_INTEGER,   <<< ADDED
  GUS_FILTER_TYPE_BINARY,  
  GUS_FILTER_TYPE_QDATETIME
} GusFilterControlType;

--------------------------
Q3GUI/GusFilterControl.cpp

NEW, instantiated for GUS_FILTER_TYPE_INTEGER:
 QSpinBox* _filterSpinBox;
