-//    qs= new QueryString(string)
-//
-//        Create a query string object based on the given query string. If
-//        no string is given, we use the one from the current page by default.
-//
-//    qs.value(key)
-//
-//        Return a value for the named key.  If the key was not defined,
-//        it will return undefined. If the key was multiply defined it will
-//        return the last value set. If it was defined without a value, it
-//        will return an empty string.
-//
-//   qs.values(key)
-//
-//        Return an array of values for the named key. If the key was not
-//        defined, an empty array will be returned. If the key was multiply
-//        defined, the values will be given in the order they appeared on
-//        in the query string.
-//
-//   qs.keys()
-//
-//        Return an array of unique keys in the query string.  The order will
-//        not necessarily be the same as in the original query, and repeated
-//        keys will only be listed once.

-//        This static method is an error tolerant version of the builtin
-//        function decodeURIComponent(), modified to also change pluses into
-//        spaces, so that it is suitable for query string decoding. You
-//        shouldn't usually need to call this yourself as the value(),
-//        values(), and keys() methods already decode everything they return.
-//
-// Note: W3C recommends that ; be accepted as an alternative to & for
-// separating query string fields. To support that, simply insert a semicolon
-// immediately after each ampersand in the regular expression in the first
-// function below.
