==============================
CRC is a C++ library which computes the PNG CRC (cyclic redundancy
checksum) for a string of bytes.
PNG is the Portable Network Graphics format.
The PNG checksum algorithm is used as part of the encoding of a PNG
file.

- CRC returns the CRC of the bytes in BUF[0…LEN-1].
- MAKE_CRC_TABLE makes the table for a fast CRC computation.
- PRINT_CRC_TABLE prints the CRC table.
- TIMESTAMP prints the current YMDHMS date as a time stamp.
- UPDATE_CRC_C updates a running CRC with one more character.
- UPDATE_CRC_S updates a running CRC with a new string of
characters.
