/**
 * @mainpage 
 * A simplified version of Blackjack.
 * \n
 * <b>Rules</b>:
 *  - There are two kinds of \c Player: \c Dealer and \c User
 *  - The dealer gets one card to start
 * (in real life, the dealer gets two, but one is face down so it doesn’t matter at this point).
 *  - Users gets two cards to start.
 *  - Dealer goes last.
 *  - A player can repeatedly “hit” or “stand”.
 *  - If the player “stands”, their turn is over, and their score is calculated based on the cards they have been dealt.
 *  - If the player “hits”, they get another card and the value of that card is added to their total score.
 *  - An ace normally counts as a 1 or an 11 (whichever is better for the total score). 
 *  - If a player goes over a score of 21, they bust and lose immediately. 
 *  - The dealer repeatedly draws until they reach a score of 17 or more, at which point they stand. 
 *  - Otherwise, the player with the highest score wins.
 *      - We don't consider ties for simplicity.
 *      - So, it can happen that both multiple players can win.
 * \n
 * <p>
 * In our simplified version of Blackjack, we’re not going to keep track of which specific cards a player has been dealt.
 * We’ll only track the sum of the values of the cards.
 * \n

/**

 * - Setup the players
 *  - Why don't we setup the players in a separate function or a separate "Service" class?
 *      - Note that the lifetimes of the \c dealer and the \c user(s) must be that of the entire program.
 *      - As long as the program is running, the game is being played; for which the players must naturally be alive!
 *  - The \c User needs to be informed of the \c playerLimit.
 *  - The \c Dealer will be told the \c dealerLimit as well.
 * - Play a game of Blackjack
 * - Reset the players
 *  - In case the players want to play another round.
