> This ticket will add support for visualization of convex hulls through the projectToBorder function and 2D clusters by adding the clusters parameter to the zplot function.
> The *projectToBorder* function is a function that works together with the existing *convexHull* function. It takes two parameters:
> 1) A Convex Hull created by the *convexHull* function.
> 2) A matrix of 2D points to project to the border.
> The projectToBorder function then projects each 2D point to the Convex Hull border and returns a matrix with these points.
> Using this approach the border of a convex hull can be visualized in interesting ways.
> Sample visualizations are attached.
