Added boilerplate code for making it easier to get started

[arjunmahishi]

I've added a simple react app code base in the boilerplate directory. I've used create-react-app to generate most of it. I have also implemented react-router.

The code will work right out of the box. Just need to "npm install" and "npm start" in the boilerplate directory.

I hope this makes sense.

Merge it with whichever branch, I selected master just like that.
