Automate your workflow with Gulp - part 2

In this part I will take to the discovery of our third section of the gulpfile.js which will allow us to `watch` our file and run our tasks runners whenever we save. Also, aside our minified css task, we are going to add the possibility of *livereloading*, *compile a sass* file instead of using raw css, then *display a notification* when everything is done successfully.
