dimensions to the given ranges.
OPTIONS

lower is the lowest (minimal) value allowed in each dimension. It defaults to -1.
-u upper
upper is the highest (maximal) value allowed in each dimension. It defaults to 1.
-y y_lower
y_lower is a boolean value (0 or 1) indicating whether or not y-values (targets) should be scaled. It defaults to 0.
-s save_filename
save_filename indicates the filename to save the scaled data to.
-r restore_filename
restore_filename indicates the filename reserved to hold the original (unscaled) data in case there is a need to restore.
