Brief Write a Caesar Cipher function. That is, write a function which: takes two inputs, a string for the message, and an integer for the shift returns a string that's just the input string with all of its characters shifted by the amount specified in the shift argument for each character in the string (including punctuation marks, special characters and capital letters) gets that character's Unicode v, and replaces it by the character with the Unicode v + shift accounts for user inputs that aren't strings is as elegant and efficient as possible
