# A utility script to set variables for use in the Weka command line.  This script sets the following variables:
#  weka_dir - the path to the weka folder
#  weka_out - the path to a folder for output files
#  train_test_args - args to identify a training and testing file, or just a training file (NOTE: this uses cross validation instead of a separate testing file)
#
