4. Implement in file craps.py a GUI that simulates the gambling game craps. The GUI should include a button labelled "New game" that starts a new game by simulating the initial roll of a pair of dice. The result of the initial roll is then shown in an Entry widget (as shown below). If the initial roll is not a win or a loss, the user will have to click the button "Roll for point", and keep clicking it until she wins.
