[docs/demos] More examples

[filipdanic]

More examples would be awesome – let your imagination run wild! :)

It would be great if:

• You could create some more interesting or well-designed examples of spicy-datatable.
• You could add react-router and make it possible to navigate between demos in a way that each demo has its own route.

Have a look at App.js to get started! :)

If you need any help, let me know – and if you want to take this issue, leave a comment. 👍

This is still open to anyone who wants to have a crack at it. :)

The demo that I recently added to CodeSandbox (https://codesandbox.io/s/ov4po21nky) can be used as a cool example/starting point for more demos. 👍
