This class can be used to manipulate query strings. This class turns your HTTP query string into an object with dynamic properties allowing you to get, set, and unset key value pairs in your query string for printing within link tags or server redirects. This class is perfect for use with pagination, sorting, or any other application in which you may be carrying over query string variables between requests, but only need to change one or two variables for a page's HTML links. NOTE: This class does NOT modify the $_GET array in any way, shape, or form. To retrieve an HTML version of the generated query string, simply print your instantiated variable. To retrieve a non-HTML entity version of the query string, use the url() method.
