Please put example code in sub directory

[StevePotter]

Hi, thanks for the great work. When I initially saw your codebase, I thought this was a React Native bridge module, but then came to understand it was a JS-only package. This is because I saw the android and ios directories. Also I was confused at index.ios.js and index.android.js files.

Typically in a RN library you put example code in a sub directory called Example or whatever. This will eliminate any confusion. If you need help, let me know and I'll create a PR for it

Thanks!

But sub directory can't import superior directory's file. Any idea? PR is welcome!
