/*The Pigs Game 

  This is a command-line implementation of the Pigs Game. 

  The rules of the game as explaned on Wikipedia are:
  Each turn, a player repeatedly rolls a die until either a 1 is rolled or the player decides to "hold":
  If the player rolls a 1, they score nothing and it becomes the next player's turn. If the player rolls 
  any other number, it is added to their turn total and the player's turn continues. If a player chooses to 
  "hold", their turn total is added to their score, and it becomes the next player's turn. The first player to 
  score 100 or more points wins.

//When this command line application is launched it asks the user how many human and Computer
//players wish to play the game. Once thoose numbers are determined it then asks the user to enter
//names for each of the human players. The computer players are automatically given names. Once
//the naming process is complete the game begins. During the naming process a new player class
//is instantiated for each player and the address of that player class is stored into a vector. WIth 
//all the players in the vector we are able to cycle through the vector and present each player a 
//chance to play the game until a winner is determined. Upon a winner being declared the 
//application ends but prior to exit the memory is freed.
