Instructions for converting from a one file game to a game 
  that uses a player class 
Step 1: 
Cut all methods except the instructions and the main method from your game 
  and put them into a new player class. Ensure your brackets are balanced.
  In player class
  
    - Add public class Player { to the top.
- Remove static from all methods.
- Add 2 instance variables: location and name.
- Change every method to use the location from itself instead of from the 
      input and update the instance variable location. 
- Remove any unnecessary inputs. 
- Create a constructor that takes in just a name and sets the location to 
      0.
- Add a getLocation method
- Add a win method 
 
  In main: 
  
    - Ask the player name and create player1 (when everything is good, you will 
      ask for player 2 also, but first get 1 working
- change all method calls to call methods on player1 with the correct number 
      of variables. 
Step 2: 
  - Ask for another player and create it right after the first one. 
- Copy everything inside your while loop to repeat the commands for player2.
- Only play for player2 if player1 hasnt won. 
- Adjust the Do you want to continue question to work for both 
    players. (You can just ask if you want to play another round instead of asking 
    each student.)
