Failed to get independant initialization of population per-replicate
when i used python's multiprocessing.process objects as hosts for
running replicates in parallel. Solution as of now,
Sat Jul 30 22:38:42 MDT 2016, is to use OS processes via python's
subprocess module, creating them in this def, which gets its
requisite info needed for the sim from the pgguisimupop instance
that calls this def (this def is called by the GUI interface instance
in a new python.multiprocessing.process instance, in order not to block the gui).
Note that this def was originally inside the pgguisimupop instance that calls it,
but on windows there was a pickling error not seen on linux or Mac. Moving this
target def for the python.multiprocessing.process outside the pgguisimupop instance
seems to have solved the problem on windows (win 10).
This def manages the replices via creating subprocesses, and
calling pgparallelopmanager.prep_and_call_do_pgopsimupop_replicate
(note: the call has been updated 2017_11_12, after the defs were
moved from pgutilities into new module pgparallelopmanager.
2017_05_30. We added the def param b_use_gui_messaging=True, to allow
this def to be called from a command line implentation (new module
pgdrivesimulation.py), and set the flag to false, without having to
revise the call from the GUI pgguisimupop.py.

Running this inside a try block allows us to notify GUI
users of exceptions propogated from anywere inside the

below, we send an error message to a gui message box, then
re-raise the exception.

to allow callers to this def to set these new parameters in the PGOpSimuPop
