 * QR Code generator test worker (Java)
 * 
 * This program reads data and encoding parameters from standard input and writes
 * QR Code bitmaps to standard output. The I/O format is one integer per line.
 * Run with no command line arguments. The program is intended for automated
 * batch testing of end-to-end functionality of this QR Code generator library.
