Draw Lines

Time to actually draw something useful on the screen!

Assignment

Create a Point class. It should simply store 2 public data members:

x - the x-coordinate (horizontal) in pixels of the point
y - the y-coordinate (vertical) in pixels of the point

The value x=0.0 is the left of the screen, y=0.0 is the top of the screen.

Create a Line class, Its constructor should take 2 Points as input, and save them as data members.
Add a draw() method to the Line class that takes a Tkinter Canvas and a "fill color" as input. The fill color is just a string like "black" or "red".
- It should call the Canvas's create_line method:

canvas.create_line(x1, y1, x2, y2, fill=fill_color, width=2)

Add a draw_line method to the Window class. It should take an instance of a Line and a fill_color as inputs, then call the Line's draw() method.
Draw a few lines on the window using your new methods in your main function, then test the program manually.
