Using the DrawingPanel class, write a C# class named Football that produces the following figure:
Though the figure looks to contain curves, it is made entirely of straight lines.
The window is 250 x 250 pixels in size, and there is an outer rectangle from (10, 30) to (210, 230).
A set of black lines are drawn around the edges every 10 pixels.
For example, along the top-left, there is a line from (10, 220) to (20, 30), a line from (10, 210) to (30, 30), a line from (10, 200) to (40, 30), ... and so on.
Along the bottom-right, there is a line from (20, 230) to (210, 220), a line from (30, 230) to (210, 210), and so on.
