DONE 1

work on my local jvm ethereum network

• write function shuffleDeck(): it will randomly shuffle uint8[52]
• write function getDeck() public

DONE 2

work on my local jvm ethereum network

• write function computeCardValue() returns uint8
• write function computeHandValue() returns uint8

DONE 3

work on my local jvm ethereum network

• write function dealerDecision() returns bytes2
• decision is Hit or Stand

DONE 4

work on my local jvm ethereum network

• write function initPlayerHand()
• write function initDealerHand()
• write function giveTwoCardsToDealer()
• write function giveTwoCardsToPlayer()

work on my local jvm ethereum network

• write function getPlayerHand()
• write function getDealerVisibleCard()

TODO 6

work on my local jvm ethereum network

TODO 7
