This is a user input widget. Let me explain how it should work:
Think of a square with a dot in the center. The user clicks the dot in the center, then hovers over one of the four corners. A line is then drawn from the center to that corner. From there, any corner the user hovers over a line will be drawn, and the user can also hover over the dot in the center to draw a line from the corner back to the center. This continues until the mouse is clicked.

Please bid on this project, as well to be considered you must answer the following:
