Minkowski Distance

The Minkowski Distance between two points is defined as:

$D(X,Y)&space;=&space;(\sum_{i=1}^{n}|x_{i}-y_{i}|^p)^{\frac{1}{p}}$

where

$n \epsilon \mathbb{N}$

n is the number of dimensions, 2 for 2D and 3 for 3D and so forth.
p is the order (1 for Manhattan distance and 2 for Euclidean distance)
