5 * arguments' order is reversed.

9 * @since v0.1.0
10 * @category Function
11 * @sig ((a, b, c, ...) -> z) -> (b -> a -> c -> ... -> z)
12 * @param {Function} fn The function to invoke with its first two parameters reversed.
13 * @return {*} The result of invoking `fn` with its first two parameters' order reversed.
14 * @example
15 *
16 * const mergeThree = (a, b, c) => [].concat(a, b, c);
17 *
18 * mergeThree(1, 2, 3); //=> [1, 2, 3]
19 *
20 * R.flip(mergeThree)(1, 2, 3); //=> [2, 1, 3]
21 * @symb R.flip(f)(a, b, c) = f(b, a, c)
