Subject: code release: cryptographic attack tool

i release my private librairy "qbytes" (quantique bytes)
this is a mathematic tool where all bits of a double word have 3 states :
one , zero and unknow
i implemented the addition , multiplication (with an integer), a new concept
"fusion" (equivalent to = ) , and all basic booleean functions (binary
version of xor, or, no , and)
there are some utilities like error detection, error depth etc ...

i used this lib for coding fuckmd5.cpp

if you want to use multithreading the code need modification

i think this tool is good for easy recomputation and error detection in the
case of a cryptographic attack

quantique.h : structure definition
qbyte.h : class definition
qbyte.cpp : all the functions
