GoLang: "fizzbuzz" is the new "hello world"

fizzbuzz.go

// fizzbuzz
// A program that prints the numbers from 1 to n. But for multiples of three 
// print “Fizz” instead of the number and for the multiples of five print “Buzz”. 
// For numbers which are multiples of both three and five print “FizzBuzz”.
