Problem 78. Implement a ROT13 cipher

Created by Cody Team in Cody Challenge

Replace each character in string s1 with the character that is shifted 13 positions from it (wrap back to the beginning if necessary). So A ? N, B ? O, and so on until Y ? L and Z ? M. Case of the output should match the case of the input, so a ? n. Non-alphabetic characters are left in place and untouched.

If

 s1 = 'I love MATLAB'

then

 s2 = 'V ybir ZNGYNO'

See the Wikipedia article for more info.
