22*	Arbitrary-precision integer arithmetic.				*
23*	For speed, we work in groups of bits, even though this		*
24*	complicates algorithms.						*
25*	Each group of bits is called a 'littlenum'.			*
26*	A bunch of littlenums representing a (possibly large)		*
27*	integer is called a 'bignum'.					*
28*	Bignums are >= 0.						*
