/**
 * Swap an item, at index `indexA` with another item, at index `indexB`, in an object or a list of elements.
 * A new result will be created containing the new elements order.
 *
 * @func
 * @memberOf R
 * @since v0.29.0
 * @category List
 * @sig Number -> Number -> [a] -> [a]
 * @param {Number|string|Object} indexA The first index
 * @param {Number|string|Object} indexB The second index
 * @param {Array|Object} o Either the object or list which will serve to realise the swap
 * @return {Array|Object} The new object or list reordered
 * @example
 *
 *      R.swap(0, 2, ['a', 'b', 'c', 'd', 'e', 'f']); //=> ['c', 'b', 'a', 'd', 'e', 'f']
 *      R.swap(-1, 0, ['a', 'b', 'c', 'd', 'e', 'f']); //=> ['f', 'b', 'c', 'd', 'e', 'a']
 *      R.swap('a', 'b', {a: 1, b: 2}); //=> {a: 2, b: 1}
 *      R.swap(0, 2, 'foo'); //=> 'oof'
