1) Design and implement the class structure for a drawing application. A drawing is made up of a canvas that contains a collection of three different shapes: circles, lines, and boxes. Each shape can be drawn by calling a Draw() method for that shape. The canvas class should also have a draw method that draws all of the shapes it contains. You dont have to actually draw anything on a screen; you can simulate drawing by writing a message to the console. For example, the code snippet: canvas.Draw(); could produce something like the following output to the console: Drawing a circle at... Drawing a line at... etc. (For each shape on the canvas)

2) (Bonus) Consider re-writing the above answer (#1) differently where the canvas does not contain the shapes, but is able to draw any of the three shapes passed to it. Re-design canvas.Draw() if you need to. Your main() program should ask for user input on what shape to draw. Ask once, draw, then exit.
