Methods

o move 
 public void move(Point p)
Takes the point p and checks if it is within the "Scramble" box. If so, it calls the private method Scramble(). If not, it determines which square has been clicked (in terms of the indices of the array) and calls a private method privateMove with the indices.

Parameters:
p - the location of the last mouse click
o draw 
 public void draw()
Draws the board and the "Scramble" box. The puzzle pieces are drawn by calling the draw method in PuzzlePiece.

o isScramble 
 private boolean isScramble(Point p)
Given a point, checks if it's inside the "Scramble" box.

Parameters:
p - the point the user clicked.
Returns:
true if p is in the box, false otherwise.
o Scramble 
 private void Scramble()
Scrambles the pieces by calling privateMove a 1000 times with randomly generated indices. (This is called from move().).

o privateMove 
 private void privateMove(int i,
                          int j)
Takes the indices and checks for the place to move the piece. This is where all the work takes place. After finding the move, the piece is moved to it's new position in the array, and it's position on the board is updated using the move method in PuzzlePiece.

Parameters:
i - the first index, ranges from 0 to 3
j - the second index, ranges from 0 to 3
