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

  And what timing, I just finished getting it working with 
assembly and compatible versions. Seems 5x slower rather than the 
dreaded 50, but that's from testing factorial up to 100 (200ms vs 
1,200ms).

  Anyways, here's how it is currently, most features are 
avaliable, need more tests and find occurrences where it doesn't 
work.

  One note, to get the x86 assembly versions, use -version=Intel, 
I have it disabled so I can concentrate on the compatible version 
and switch between them on my machine. -debug includes a unittest 
that runs a factorial test
