This component is quite useful and it would be great if you submit it to http://craftycomponents.com/components/addNew.
I tried to do that already, but there is a little problem with the package.json file.
Earlier, I was pointed out by @mucaho that a wrongly placed comma was the reason for this.
So, I think you just need to remove the comma after the item - bounding.
At least this is what http://jsonlint.com/ says ;)
I fixed the error and submitted it to Crafty Components.
I removed the underscore string dependency along the way :-)
