| * 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. * |
