/**
 * Returns a new function much like the supplied one, except that the first two
 * arguments' order is reversed.
 *
 * @func
 * @memberOf R
 * @since v0.1.0
 * @category Function
 * @sig ((a, b, c, ...) -> z) -> (b -> a -> c -> ... -> z)
 * @param {Function} fn The function to invoke with its first two parameters reversed.
 * @return {*} The result of invoking `fn` with its first two parameters' order reversed.
 * @example
 *
 *      const mergeThree = (a, b, c) => [].concat(a, b, c);
 *
 *      mergeThree(1, 2, 3); //=> [1, 2, 3]
 *
 *      R.flip(mergeThree)(1, 2, 3); //=> [2, 1, 3]
 * @symb R.flip(f)(a, b, c) = f(b, a, c)
