title: Canvas Class Constructor Function
body: <p>I am working on an assignment involving classes. I have completed the two other class that have been asked of us: Point, and Rectangle. I am currently working on the canvas class and I am not sure what to put in its constructor. The purpose of the canvas is to store rectangles that you have added to the canvas and compare them through multiple functions.</p>
  
  <p>My question is, how do i create a constructor for this class if there is nothing originally in it</p>
