Description Author

This class can find a convex shape that contain a set of points known as the convex hull.

It takes a set of points in a two dimensional plane and uses the convex hull algorithm to calculate the coordinates of the edges of a shape that contains all the points in the set.

Another class can render the points and the convex hull shape as an image file in the PNG format.
