Why this be overridden? Maybe this is worth adding as a comment.

[jasonsanjose]

Done with initial review

Thanks Randy. Just pushed my changes. I did a good amount of refactoring to for usage of encode/decode URI component.

[redmunds]

I think this utility would be more useful if the url string were passed in as a parameter. That way it could be used for any url, not just the current document.

[jasonsanjose]

Added an optional url parameter. Defaults to window.document.location.search.

[redmunds]

Nice refactoring. Just a couple more minor comments.

[jasonsanjose]

Thanks @redmunds. Updated the docs too. Ready for review.
