Caesar Cipher

The Caesar Cipher is a way of encoding a message by replacing its letters with a alphabet that has been shifted a number of letters forward. I created this code to both solve and encode a message with the caesar cipher. The most common way of solving the caesar cipher is to brute force and find every possible combination and see which makes sense by hand. However, my program makes use of frequency analysis to find which combination is more probable to be a actual word. However, Since this is only a estimation of what the correct answer is, the program is not 100% accurate.
