support collapse and expand on nested objects

Thanks to JSONHERO, it is really easy to switch between elements in an array to see the difference. Great tool, thank you guys!

I've only one issue, when the JSON is big and I'd like to compare multiple elements, I'd like to be able to collapse nested objects, just like in IDEs. It would also help to see structure of the JSON.

Thanks.
