Description
Define a QueryString that you can build on and then output with your links. You can add an additional item at the time of output that won't be built into the existing object.
Sample Usage
var('query_string' = QueryString);
$query_string->add('sort=price');
$query_string->add('city=Livermore');
$query_string->output('skip=' + $skip++);
outputs: ?sort=price&city=Livermore&skip=0
