//next Thr quiz in lecture

TicTacToe t = new TicTacToe();
TTTWindow w = new TTTWindow(t);
t.setMark('X', 1,1)
w.update(1,1)

//instead of doing this manually, we write a "main" method
//    public static void main(String[] args) 
//this is the starting point of the program
//After compiling, to run simply type: java programname
//where programname is a .class file containing the main method

//also, you can pass arguments to the main method:
//  java myprog arg1 arg2 ...
//then in the main method args[0] is arg1, args[1] is arg2 and so on

//exercise: make the driver more robots:
   1. if the use enters non-numbers or out of range row/column ask agian
      until row and column are valid.
   2. if the row/column is valid but already occupied, tell user to choose an 
      empty cell, and keep asking for a valid cell.
      The best way to do this is to change the setMark() method to return true/false
      (false if the cell is not BLANK), so in the driver if you setMark
      and it is false you know the cell was not BLANK.
