Is there a good lib out there to handle large integer of know size ?

  Got a possible one. My implementation is heavy on assembly 
language to take advantage of x86 features (like the carry flag, 
and giving you 64 & 128bit inputs/results). Still building it, 
but it's promising, mostly got cleanup on it to do and more 
unittests.

  Honestly the hardest part is writing the division code, which I 
think I just got done.
