// SimpleFraction is used to represent simple (or "common") fractions, composed
// of a rational number written a/b where a and b are both integers.
// Some helpful notes on SimpleFraction assumptions/limitations:
// 1. SimpleFraction does not perform reductions. 2/4 != 1/2, and -1/-1 != 1/1.
// 2. denominator = 0 is considered undefined.
// 3. numerator = saturates range to int min or int max
// 4. A SimpleFraction is "positive" if and only if it is defined and at least
//    equal to zero. Since reductions are not performed, -1/-1 is negative.
