-# This file contains internal Pmetrics utility functions
-# BUG FIX wmy.2017.04.12 The Femke error polynomial quandry.
-#
-# wmy.2017.04.12
-#
-# Symptoms:
-# For NPrun(...data=RunNo...) the RunNo/wrk/working_files are copied to the new
-# NPAG run. The working files include an error polynomial. NPAG
-# uses this error polynomial instead of the error function requested in the
-# model.txt file for the new optimization.
-#
-# Relevant observations:
-# 1) NPprep() reads the name of the model.txt file, just prior to
-# determining if data=RunNo or a new *.csv file.
-#
-# Solution: Immediately after determining that data=RunNo AND is.integer(RunNo) == T,
-# compare the #ERR block of /RunNo/input/model.txt to the model.txt for the current
-# run. If equivalent, no problem -- if different, then use the /RunNo/input/*.csv
-# as a "new" dataset and generate working files from it.  Soution reqs the following
-# two utility functions:
-# 1) compareTwoModelERRs <- function(mod1,mod2)
-# 2)
-
-#
-# This function compares two model.txt file #ERR blocks and returns T/F if
-# the same or different, respectively.
-#
-# Below is MN's code as of 12/3/18

-#    to compare old instructions to a new NPAG run instructions.  Therefore,

-#    if an instr is a valid phrase, if old.data is an integer, REM* is the
