Improve with Insertion Sort #7
Description
In a divide-and-conquer algorithm, it is advisable to use a simpler algorithm when subproblems become small enough, since the constant factor in a divide-and-conquer algorithm is usually larger than a simpler one.
As for the algorithm we implemented, it can be improved by using insertion sort when the number of points becomes sufficiently small.

Please improve your implements if it is convenient to you.
For your reference, improve cpp with insertion sort.
