RSGuessGame.java

  //Programmer: Ryan Seefeldt 
  //Class: CS& 141
  //Date:7/6/2023
  //Purpose: This is a guessing game to guess a number from 1 to x 
  //    where x is a class constant. This will allow you to enter 
  //    as many guess as you like up to 9999. After each guess 
  //    you will be told if the number is higher or lower than 
  //    your guess. Once the number is guessed correctly the 
  //    program will print the number of guess and you will be 
  //    asked if you would like to play another game. you can enter 
  //    any string beginning in Y,y,N,n and only the first 
  //    character will be used to determine if you will play on. 
  //    After you enter n or N as the first character the game 
  //    will end and print out statustics for the game. 
  //    Statistics printed: Total games played, total number 
  //    of guesses, average number of guess for the games played, 
  //    and lowest number of guesses used in all games played 
  //    that session.
  
  //Extra Credit: none
  
  //Issues in the code:
