Title: Calculate Checksum (CRC32 and CRC16)
Description: Yesterday, I was lookin' for some code to compute a CRC32 checksum value but could not find any fast working code here. So I made this class file that allows you to calculate real CRC32 checksums. I also needed *FAST* code so this uses assembler code that you can use without actually knowing any assembler. This code is able to compute 56 MB/s on a P3 600Mhz!!
