//
//  Purpose:
//
//    MAIN is the main program for LATINIZE_TEST.
//
//  Discussion:
//
//    LATINIZE_TEST tests the LATINIZE library.
//
//    The dataset is presumed to be an M by N array of real numbers,
//    where M is the spatial dimension, and N is the number of sample points.
//
//    The dataset is presumed to be stored in a file, with N records,
//    one per each sample point.  (Comment records may be included, 
//    which begin with '#'.)
//
//    The program reads the data file, "latinizes" the data, and writes
//    the latinized data to a new file.
//

//
//    This code is distributed under the MIT license.
