Usage

This is a mixin so once you've included the source code, simply mix it in to any react component you want to start monitoring.

E.g.

var ReactRenderVisualizer = require("react-render-visualizer");

app.TodoItem = React.createClass({
    mixins: [ReactRenderVisualizer],

Component will show up with a blue border box when being monitored
