'''
An identity matrix is defined as a square matrix with 1's running from the top left of the square to the bottom right. The rest are 0's. The identity matrix has applications ranging from machine learning to the general theory of relativity. 

Identity Matrix:
-----------------
Input :  4
Output : 1 0 0 0
         0 1 0 0
         0 0 1 0
         0 0 0 1

Mirror Identity Matrix:
----------------------
Input :  4
Output : 0 0 0 1
         0 0 1 0
         0 1 0 0
         1 0 0 0
