* Once we have the closed path, the next step is to traverse the path and
* remove concave points on this path using orientation. The first two points in
* sorted array are always part of Convex Hull. For remaining points, we keep
*track of recent three points, and find the angle formed by them. Let the three
*points be prev(p), curr(c) and next(n). If orientation of these points
*(considering them in same order) is not counterclockwise, we discard c,
*otherwise we keep it.
