store form values in URL params
===

I have a d3 chart with some `<input>` elements for configuration. I'd like these configuration options to update URL params as they're changed, and obviously when the page is loaded these URL params should be used as default values.

This seems like a basic piece of functionality on a lot of sites, is there a jQuery library out there (I couldn't find one) that I could just drop in? Or do I need to roll my own.

Thanks!
