 * Move an item, at index `from`, to index `to`, in a list of elements.
 * A new list will be created containing the new elements order.

 * @func
 * @memberOf R
 * @since v0.27.1
 * @category List
 * @sig Number -> Number -> [a] -> [a]
 * @param {Number} from The source index
 * @param {Number} to The destination index
 * @param {Array} list The list which will serve to realise the move
 * @return {Array} The new list reordered
 * @example
 *
 *      R.move(0, 2, ['a', 'b', 'c', 'd', 'e', 'f']); //=> ['b', 'c', 'a', 'd', 'e', 'f']
 *      R.move(-1, 0, ['a', 'b', 'c', 'd', 'e', 'f']); //=> ['f', 'a', 'b', 'c', 'd', 'e'] list rotation
