Example of a Manager Class 
==========================

Let's consider the card game in more detail.
Suppose you have a Card class and a CardDeck class that held an array of Cards.
CardDeck might have a shuffle() method.

There's also a Player class that would makeBid(), playCard(),
evalHand() in a card game such as bridge.

Here's an outline of the class BridgeGame:
   class BridgeGame {
      methods:
         appropriate gets and sets
         playGame
         dealCards
         determineIfWin
      data:
         Deck theDeck;
         Player thePlayers[SIZE];
         int numOfPlayers;
   }

The most important methos is playGame():
   void BridgeGame::playGame() {
      theDeck.shuffle();
      deal();

      loop to win bid {
         for (int i = 0; i < SIZE; i++) {
            thePlayers[i].makeBid(...);
         }
         exit when bid is won;
      }

      loop to play hand {
         for (int i = 0; i < SIZE; i++) {
            thePlayers[i].playCard(...);
         }
         for (int i = 0; i < SIZE; i++) {
            determineIfWin(...);
         }
      }
      handle win
   }

Even if you don't know how to play bridge, you get the idea.
The main is very short, common in OO programming:

   int main() {
      BridgeGame g;
      g.playGame();
      return 0;
   }

The manager class, BridgeGame, owns the data and manages the running
of the game. In a business, the data is owned (container objects
holding the business data) and the running of the business would be managed.
