Note to streaming examples

Thanks for making those good examples to see how something is working. I tried to work with the streaming example chatter/chatter-cli and I was wondering in the beginning, why the client app did not work as described in the Readme. It took me some time to find the correct branch which had the chatter-cli implemented the functionality which is described.

In order for new people it would be easier if the master version of "chatter-cli.go" has the code of the branch: "testing_poc" included to have a working example out of the box.

I would be happy to prepare the changes to outsource the working on the stream into a new file in the package main which shows how to deal with the streams, if that's ok?
