 This plugin attempts to make working with querystrings easier. The primary function exposed is `$.querystring`, which handles both parsing & serialization (depending on the type of argument passed in). A `$.fn.querystring` method is also provided, which makes getting & setting the querystring of `<a>` elements more convenient.
