Bug 5963: Rpl Series Slot: Sync Range with Run Period needs to include Initial Timestep
Bug Number: 5963
Release notes (y/n): Yes
For Release Nums: 7.0.8 and 7.1

Gnats 5963: Always sync with run period fails excludes initial timestep 
  for series slots with expressions.

*** This commit requires more testing. [Phil, 5-23-2017] ***

When RPL Series Expression Slots are set up to synchronize the time range 
to the Run Period, the Initial Timestep (one timestep before the Start 
Timestep) needs to be included in the series slot's new time range.

A provisional change was made in Sim/SeriesSlot.cpp, in method: 
okstat SeriesSlot::p_synchSeriesWithExprData(), in the clause where 
'getExprSynchWithRun()' is true.
