I wanted to ask what exactly we have to do in programming competency test for Project 1. It states that implement and test "Gift wrapping" Convex hull for MultiPoint Concept, so I need to design a new strategy for convex hull (strategy::convex_hull::gift_wrapping) or implement a new algorithm (convex_hull_gift_wrapping), and that too only for MultiPoint Concept? And also this algorithm should be implemented for cartesian coordinate system only, or any other systems also? Also I need to make a PR for this (with doxygen commands) or make a different repository for this? And at last, testing will include checking the code output with different existing algorithms? Thanks, in advance!
