Title: Replace references to CFAbsoluteTimeGetCurrent with CACurrentMediaTime

http://nshipster.com/benchmarking/

seems to have been written first with CFAbsoluteTimeGetCurrent but later had that call replaced with CACurrentMediaTime in the example. There are still lingering references to CFAbsoluteTimeGetCurrent that should be replaced with CACurrentMediaTime.
