What is it about?
A simple method to reduce the number of points before computing the 2D convex hull of those points. It assumes point with integer coordinates.

Why is it important?
It makes computing the 2D convex hull faster regardless of the algorithm being used under certain conditions mostly met in most practical data sets.
