A modification for 'React.js Essentials' book. - no need for snapkite-engine server

mockTweets.js

/* I wrote this to help me with the project in the React.js Essentials book by Artemij Fedosejev.  
I couldn't get the snapkite-engine to work but wanted to test the project out on my machine. 
So this can be added to the project so you don't have to create the snapkite-engine server. 
You only have to change one require statement in the Stream.react.js file. */

/* create a mockTweets.js file in the source/components directory of the project */

/*
in the /source/components/Stream.react.js file, change the line that starts with 'var SnapkiteStreamClient=' 
to the following:

var SnapkiteStreamClient = require('./mockTweets');

That's it.  Run the default gulp task and you should get a random tweet every 5 seconds when 
you start the project.
