+ * 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. *
