/**
 * Creates a function that will process either the `onTrue` or the `onFalse`
 * function depending upon the result of the `condition` predicate.
 *
 * @param {Function} condition A predicate function
 * @param {Function} onTrue A function to invoke when the `condition` evaluates to a truthy value.
 * @param {Function} onFalse A function to invoke when the `condition` evaluates to a falsy value.
 * @return {Function} A new unary function that will process either the `onTrue` or the `onFalse`
 *                    function depending upon the result of the `condition` predicate.
 * @example
 *
 *      const prop = ifElse(
 *        x => x.a,
 *        x => x.b,
 *        x => x.c
 *      );
 *      prop({ a: false, c: 2 }); //=> 2
 *      prop({ a: true, b: 1, c: 2 }); //=> 1
