Update Example Code in Readme

[palamccc]

I installed react-sidebar today and got version 2.1.1 from npm. I think latest version uses new es7 module syntax.

But Readme in github uses commonjs syntax.

The ES2015 class is the source code but the package.json points at the ES5 version. No need to update it.

Few hours ago, I installed it, and require('react-sidebar') is not working. to make it work, i am actually using it as

var Sidebar = require('react-sidebar').default;

Instead of

var Sidebar = require('react-sidebar');

I am not good in new module syntax, But in below file, there is no module.exports , so just require('react-sidebar') wont work.

@balloob Curious, why did you close this issue? Seems like it might be a good idea to at least update the readme. Since ES6 modules are still fairly new, it might be a good idea to instruct folks using ES5 that they will need to write require('react-sidebar').default || require('react-sidebar');. Your current solution will only import properly as-is if the consumer us using an ES6 transpiler that can interpret the __esModule flag (such as babel)

My bad. Both of you are right. Updated the README: 4241bbd
