This week is all about different sorting methods. The purpose of this lab is to put a vector of coordinates in order. The order is specified by the distance from the centroid of the group of points. For purposes of this lab the selection sort is well adapted to solve this problem and will be the algorithm that you must use. You will be given a vector of points in the x$,$y plane. There is a test bench to verify your code. You will need to implement the following functions
