//  Prints a listing of data folders and waves and their sizes to the history area.
// Numeric and string variables are ignored.
//
// NOTE: In a very large experiment, this can take a long time.
//
// Example:
//      PrintDataListing(root:, 0, 0, 1)    // Print all waves in root and all sub-data folders
//
// Waves that consume fewer than minWaveNumBytes are skipped. For example, to list only
// waves containing 10 million bytes or more, pass 10E6 for minWaveNumBytes.
