[Examples] Provide some working demo

[vinitshahdeo]

It will be great if you provide an example to demonstrate how to run Jasmine tests(which are currently run by opening SpecRunner.html) headlessly with Headless Chrome and gulp.

Add few sample specs for Jasmine tests with SpecRunner.html and explain step by step - how to integrate erik. A similar demo like this can be taken.

It will be helpful for beginners like me.

Thanks:)
