generates a set of files by doing ASCII same size substitutions on an original file, controller by a csv file
CSV FORMAT :
FILE NAME changes.csv
first row: ignored (colum names)
first column: filenames
Second row: original file name, strings to search
rest of rows: generated filename, strings to replace
USE
put this script, the csv and original file original in same folder, generated files go to the same folder
