```
public Polygon modify(Polygon p,
                      double threshold)
```
    Modifies a polygon by reducing the total amount of points that describe it to threshold * original number of points. Assumes that the threshold is less than 1. If it larger than 1, then it is replaced by 1/threshold. The reduction is carried out randomly by "flipping a coin".
    
    Parameters:
    
    p - Polygon
    
    threshold - of distance
    
    Returns:
    
    polygon, the modified polygon
