/**
 * Makes a comparator function out of a function that reports whether the first
 * element is less than the second.
 *
 * @func
 * @memberOf R
 * @since v0.1.0
 * @category Function
 * @sig ((a, b) -> Boolean) -> ((a, b) -> Number)
 * @param {Function} pred A predicate function of arity two which will return `true` if the first argument
 * is less than the second, `false` otherwise
 * @return {Function} A Function :: a -> b -> Int that returns `-1` if a < b, `1` if b < a, otherwise `0`
 * @example
 *
 *      const byAge = R.comparator((a, b) => a.age < b.age);
 *      const people = [
 *        { name: 'Emma', age: 70 },
 *        { name: 'Peter', age: 78 },
 *        { name: 'Mikhail', age: 62 },
 *      ];
 *      const peopleByIncreasingAge = R.sort(byAge, people);
 *        //=> [{ name: 'Mikhail', age: 62 },{ name: 'Emma', age: 70 }, { name: 'Peter', age: 78 }]
