/**
 * ap applies a list of functions to a list of values.
 *
 * Dispatches to the `ap` method of the first argument, if present. Also
 * treats curried functions as applicatives.
 *
 * @func
 * @memberOf R
 * @since v0.3.0
 * @category Function
 * @sig [a -> b] -> [a] -> [b]
 * @sig Apply f => f (a -> b) -> f a -> f b
 * @sig (r -> a -> b) -> (r -> a) -> (r -> b)
 * @param {*} applyF
 * @param {*} applyX
 * @return {*}
 * @example
 *
 *      R.ap([R.multiply(2), R.add(3)], [1,2,3]); //=> [2, 4, 6, 4, 5, 6]
 *      R.ap([R.concat('tasty '), R.toUpper], ['pizza', 'salad']); //=> ["tasty pizza", "tasty salad", "PIZZA", "SALAD"]
 *
 *      // R.ap can also be used as S combinator
 *      // when only two functions are passed
 *      R.ap(R.concat, R.toUpper)('Ramda') //=> 'RamdaRAMDA'
 * @symb R.ap([f, g], [a, b]) = [f(a), f(b), g(a), g(b)]
