class providing URI query string manipulation
 URI::Query provides simple URI query string manipulation, allowing you
 to create and manipulate URI query strings from GET and POST requests in
 web applications. This is primarily useful for creating links where you
 wish to preserve some subset of the parameters to the current request,
 and potentially add or replace others. Given a query string this is
 doable with regexes, of course, but making sure you get the anchoring
 and escaping right is tedious and error-prone - this module is simpler.
