Allow interaction with codemirror object from parent.

• Allow parent component to interact with code mirror instance created in the child.
• Updated build

I needed this for my project and i thought others might need it too.

Thanks @JodusNodus, I'll add a check to make sure interact is defined, but otherwise looks good 😃

Actually... edit

Wouldn't it be cleaner (and more React-y) to just use a ref for the react-codemirror component, and use its getCodeMirror method on the parent component's componentDidMount to interact with the CodeMirror instance?

This basically provides the same effect without the need for an interact prop:

// ... componentDidMount (){this.refs.cm.getCodeMirror().doSomething()}, render (){return <CodeMirror ref="cm" />} // ... 

[JodusNodus]

Indeed that looks better. Just tested that and that seems to work great. Thanks, didn't know you could acces the component methods using the reference. 👍

Glad that resolves it - I've rolled the change back and updated the docs to make it clearer.

This is actually still in the example code: https://github.com/JedWatson/react-codemirror/blob/master/example/src/example.js#L39 && https://github.com/JedWatson/react-codemirror/blob/master/example/src/example.js#L50
