it would be neat to have a built in way of selecting the paths the js/css hooks should be applied on. as opposed to checking if the current path matches the paths the plugin is supposed to be running in via CGI (`$self->{cgi}->script_name =~ m/addbiblio.pl/`) ps: especially since the CGI way requires you to initalize `$self->{cgi} = CGI->new` manually (possibly depending on the actual hook that is used)
