Implement Minkowski Difference

Description

The Minkowski distance or Minkowski metric is a metric in a normed vector space which can be considered as a generalization of both the Euclidean distance and the Manhattan distance. It is named after the Polish mathematician Hermann Minkowski. https://en.wikipedia.org/wiki/Minkowski_distance

This metric is useful in the field of machine learning to judge the similarity between data points. It's also employed for collision detection in game engines.
