@michalmikolajczyk I'd appreciate your feedback

Basically the work looks really cool!

1. I would suggest we refer to Airbnb style guide https://github.com/airbnb/javascript for both JS and React. I will add an eslint file.
2. I am not sure if we should load the full ui-kit package. We don't need the rtl file, and I don't really see us modifying the package – perhaps the minified files would suffice?
3. we need to have proper unit test coverage of all files with business logic

in fact, can we use ui kit from npm?

I applied another commit, now we use ui kit from npm.
