CodeAcademy - Getting Started with BJ - BJ Deal 'em Up Sec 2/2, Ex 7/7

/* 7. You're such an ace
We have one last special card to take care of, and that is 
the ace. In real Blackjack, aces are worth either 11 or 1, 
whichever helps your hand out more.

For now, let's again simplify by pretending aces are always 
worth 11.

Modify getValue to check if we have an ace, and return 11 
points if we do. An ace is represented by a 1 in our game.

We now have the basics of dealing and scoring a hand!

As you do the next lessons, think about how what you learn 
could improve our Blackjack game. We will return to it in a 
few weeks to make it even better.
