Bug 5905: AggSeries Slot Add Column Operations Missing 
Bug Number: 5905
Release notes (y/n): Yes
For Release Nums: 7.0.4

For AggSeriesSlots from pre-7.0 RiverWare models (as discovered and reported 
in this bug report by Caleb) the open slot dialog was not presenting the 
column addition and deletion operations.  This was due to the introduction 
of "custom slots," now available on all simulation objects (no longer on 
only Data Objects) in RiverWare 7.0.

The visibility of these operations depends on the slot having a "column 
block" size of 1 or greater.  In RiverWare 6.9 and prior versions, 
AggSeriesSlots on data objects where given a column block size of 1 in 
the simObjCmd (Tcl-processing) function in SimObj.cpp.  But I instead 
fixed this problem by assigning that property to custom AggSeriesSlots in 
the same place where that is done for TableSlots, in method SimObj::
createDynamicSlot().
