Write a function caesar() that will return the input message with each character shifted to the right n times in the alphabet. Make sure the encoded message is in all caps since the Romans didn't use lowercase letters. Only punks use lowercase letters.
Example : 'James is the greatest at kumite!' => 'MDPHV LV WKH JUHDWHVW DW NXPLWH!'
Make sure to preserve the spaces and punctuation of the original message, you know, for clarity's sake.
