* Arbitrary-precision integer arithmetic. *

* For speed, we work in groups of bits, even though this *
|
|
* complicates algorithms. *
|
|
* Each group of bits is called a 'littlenum'. *
|
|
* A bunch of littlenums representing a (possibly large) *
|
|
* integer is called a 'bignum'. *
|
|
* Bignums are >= 0. *
