Recreating Columns in Spritekit - Episode 06: Cycling gems

Welcome to this new series!
In this series we'll recreate the classic game 'Columns' using Swift and SpriteKit. We'll make a game that is playable using gestures in iPhones.

In this episode we'll implement the second aspect of controlling the game: cycling the falling gem stack. Also, we refactor some tests and we improve the games responsiveness. Next episode, we’ll work on detecting matches (as this is in essence a match-3 game).
