OOP's - I screwed-up
I was incorrectly "0"-ing a byte - It all seemed correct ...
The documentation for the CRC Table said the Polynomial it was using was not the
one we needed...
The CRC Table was using the correct Polynomial X^16 + X^15 + X^2 + 1 - I just
wrote incorrect code :(

The MS CryptoAPI has all the standard hash functions (MD5, SHA1 etc).
Probably overkill for most CRC Checks though.

I have an MD5 function which works on a stream (wrote it myself even :-) ).
