// # Blackjack Problem
// Blackjack is a card game played between a Player and a Dealer.
// It is played with a single Deck of 52 Cards.
// Cards have a Suit of either: "Club", "Diamond", "Heart", or "Spade"
// Cards have a Face of either: 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King, or Ace.
// The Cards have a Value based on their Face according to:
// | Face | Value |
// | ----- | ----- |
// | 2 | 2 |
// | 3 | 3 |
// | 4 | 4 |
// | 5 | 5 |
// | 6 | 6 |
// | 7 | 7 |
// | 8 | 8 |
// | 9 | 9 |
// | 10 | 10 |
// | Jack | 10 |
// | Queen | 10 |
// | King | 10 |
// | Ace | 11 |
// Both the Player and the Dealer have their own Hand of Cards. The Hand starts out empty at the start of the Game. The Dealer is dealt two cards from the deck and placed into its hand. The Player is dealt two cards from the deck and placed into their hand.
// The total value of a hand is the sum of the values of all the cards in the hand.
// When the game starts the Player is given a choice to Hit or Stand.
// If the player Hits a card is dealt from the deck and placed in the player's Hand.
// This continues while the player keeps on choosing Hit or if the player's hand Value exceeds 21 and the player busts and the game ends.
// If the player Stands (not Hit) and the player has not busted then the dealer plays.
// The dealer will continuously be dealt cards from the deck until it's hand value exceeds 17.
// If the Dealers hand is more than 21 it has Busted and the game ends.
// We compare the Value of the Players Hand to the Dealer Hand and whomever has a higher value, but not more than 21, wins.
// # Examples
// The player's hand contains 3H, 4C for a total value of 7. The player hits and is given the 10S. Hand value is now 17. Player STANDS. Dealer reveals a hand consisting of the 7D and the 5H for a total value of 12. The dealer HITs and is dealt a 10C. Dealer hand value is now 22. Dealer busts and game is over.
// The player's hand contains 10H and the AH (Ace of Hearts) for a total value of 21 (Blackjack). The player stands. The dealer is dealt the 7S and the 7H for 14. The dealer hits and is dealt a 6C for a total of 20. Since this is more than 17 the Dealer stays. The Player's Hand is 21 and the dealer Hand is 20 so the Player wins.
// ## More examples
// # Data Structure
// The following Nouns exist in the description of the "P"roblem:
// - Deck
// - Card
// - Hand
// - Player
// - Dealer
// These have the following STATE (properties) and BEHAVIOR (methods)
// - Deck
// - Properties: A list of 52 cards
// - Behavior: Make a new deck of 52 shuffled cards. Deal one card out of the deck.
// - Card
// - Properties: The Face of the card, the Suit of the card
// - Behavior: The Value of the card according to the table in the "P"roblem part
// - Hand
// - Properties: A list of individual Cards
// - Behavior: a TotalValue representing the sum of the individual Cards in the list. Add a card to the hand
// - Player
// - Properties: a single Hand
// - Dealer
// - Properties: a single Hand
// - Game
// - Properties: the Dealer, the Player, the Deck
// - Behavior: Play
// Notes: Since the Player and the Dealer just have one property we may not need those and we could skip them and just use the Hand.
// Notes: We might put all the logic for the game into a `Game` class and have it be able to play.
// # Algorithm
// 1. Create a new deck
var deck = new Deck();
// 2. Ask the deck to make a new shuffled 52 cards
deck.MakeCards();
// 3. Create a player hand
var playerHand = new Hand();
// 4. Create a dealer hand
var dealerHand = new Hand();
// 5. Ask the deck for a card and place it in the player hand
var firstCard = deck.Deal();
playerHand.Accept(firstCard);
// 6. Ask the deck for a card and place it in the player hand
var secondCard = deck.Deal();
playerHand.Accept(secondCard);
// 7. Ask the deck for a card and place it in the dealer hand
var firstCardForDealer = deck.Deal();
dealerHand.Accept(firstCardForDealer);
// 8. Ask the deck for a card and place it in the dealer hand
var secondCardForDealer = deck.Deal();
dealerHand.Accept(secondCardForDealer);
// 10. If they have BUSTED, then goto step 15
