Fastest way to list children: childNodes vs children vs firstChild/nextSibling vs firstElementChild/nextElementSibling v2 fixed

Result: firstElementChild is the fastest yielding 3-4X performance. With lastElementChild close (margin of error) 2nd. Other observations: doing for loop i-- with children shows ~150% higher performance vs i++. And unloading it into a variable prior yields another ~200% boost
