/**
* Returns a new list, composed of n-tuples of consecutive elements If `n` is
* greater than the length of the list, an empty list is returned.
*
* Dispatches to the `aperture` method of the second argument, if present.
*
* Acts as a transducer if a transformer is given in list position.
*
* @func
* @memberOf R
* @since v0.12.0
* @category List
* @sig Number -> [a] -> [[a]]
* @param {Number} n The size of the tuples to create
* @param {Array} list The list to split into `n`-tuples
* @return {Array} The new list.
* @see R.transduce
* @example
*
* R.aperture(2, [1, 2, 3, 4, 5]); //=> [[1, 2], [2, 3], [3, 4], [4, 5]]
* R.aperture(3, [1, 2, 3, 4, 5]); //=> [[1, 2, 3], [2, 3, 4], [3, 4, 5]]
* R.aperture(7, [1, 2, 3, 4, 5]); //=> []
