#handScore ⇒ Object

Extend the Array class to create a handScore method It sorts the array so that the Aces are at the end. Aces are initially assumed to have a score of 11. Basically, if the score of the hand is > 21 and we’re working with an Ace, make the ace 1 not 11. Also, if we encounter an Ace and we’re not at the end of the hand, we take that into consideration by subtracting the value of the remaining Aces. Only really for the unlikely event we get a 10 an Ace and another Ace
