Title: short list of piped stream's interactions

I saw these described incorrectly in some places, i.e.[in this slide presentation](http://www.slideshare.net/atcrabtree/functional-programming-with-streams-in-nodejs) (slide 14).

Therefore, although the code is short and easy to understand I feel it is helpful to outline these interactions quickly.
