Kata: FizzBuzz in Clojure using cond->

To learn how to use the cond-> macro, I did the FizzBuzz kata with it:

	(ns fizz-buzz-bang.core)
	(defn- divisible-by? [divisor number]
	(zero? (mod number divisor)))
	(defn say [n]
	(cond-> nil
	(divisible-by? 3 n) (str "Fizz")
	(divisible-by? 5 n) (str "Buzz")
	(divisible-by? 7 n) (str "Bang")
	:always (or (str n))))

I also added this example to ClojureDocs cond-> documentation.
