/**
* ap applies a list of functions to a list of values.
*
* Dispatches to the `ap` method of the second 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)]
