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

As previously supported, the time range of Series Slots with Expression 
(RPL Series Slots) can be automatically synchronized with the Run Period 
when evaluated.  (And evaluation can be set to be automatic, e.g. at the 
completion of each run).  In RiverWare 7.0 and prior versions, the actual 
time range applied to the RPL Series Slot was from the Run Start DateTime 
to the Run End DateTime (i.e. excluding the prior "Init" timestep).

Gnats 5963 originally requested that this time range be changed to the "Init" 
timestep (as is supported by the manual "Sync With Run Period" operation for 
conventional Series Slots).  This, however isn't always desirable.  So, for 
RiverWare 7.1, we have added a persistent option, settable independently 
for each RPL Series Slot, to start at the Run Init Timestep when synchronizing 
the time range to the Run range.

See the new "Include Initial Timestep in Run Period" checkbox in the 
Configure Timeseries dialog for RPL Series Slots.  The default for both newly 
created RPL Series Slots and those loaded from a model saved in prior 
RiverWare versions is OFF -- this preserves the prior behavior.  Also shown 
here is that dialog for a conventional, user defined, Series Slot.

Note that the "Sync Range with Run Period" operations -- both manual and 
automatic ("always") -- leave the slot's configured timestep SIZE (e.g. 
"daily") unchanged.  If necessary, the resulting begin and end times are 
adjusted to fall on a timestep boundary for the configured timestep size.

An initial implementation of this feature was merged to RiverWare 7.1 
development on 5-25-2017 (about two weeks prior) ... 
2b8cebd00891b18e26c768b9933ce30db143ce61.  That commit including the 
serialization of this new checkbox setting (e.g. as represented within the 
model file).  This adds a single line for each RPL Series Slot, for example:

  "$s" syncWithRun-InclInitTstepInRunPeriod 1

Today's merge (onto VS2013 before the merge of that branch to RiverWare 7.1)
has some substantial changes to address some problems and deficiencies with 
that initial implementation.

Today's squash merge (of the Bug5956-C temporary branch onto VS2013 before 
the merge of that branch to RiverWare 7.1) has some substantial changes to 
address some problems and deficiencies with the initial implementation (of 
two weeks ago).
