* <p>Object with extended date parsing and formatting capabilities.
* This library borrows many concepts and ideas from the Date Instance
* Methods by Ken Snyder along with some parts of Ken's actual code.</p>
*
* <p>jsDate takes a different approach by not extending the built-in
* Date Object, improving date parsing, allowing for multiple formatting
* syntaxes and multiple and more easily expandable localization.</p>
