Destructor

void ~Path (void)

virtual Destructor

All of the Points on a Path are created by create_new<Point>(), which allocates them dynamically on the free store. Therefore, the destructor calls delete() on all of the pointers on points. Following this, it calls points.clear() and connectors.clear(). draw_color and fill_color may or may not have been allocated on the free store, so ~Path() checks this first, and deletes them, if they were. Then, it sets them to 0.
