Multiplexing fizzbuzz

By Chee Leong I’m trying to show the common pattern of multiplexing via gochannel and goroutine. Definition Fizz buzz is a group word game for children to teach them about division.[1] Players take turns to count incrementally, replacing any number divisible by three with the word "fizz", and any number divisible by five with the word "buzz". Attention! Go Playground operation is single threaded hence output is always in order of the input.
