Hack of mod_banners.php for Joomla's banner component. It will display the one banner with the least impressions or clicks (to be configured in the back-end). In the "least impressions made" configuration, this module will display all banners at a equal rate. This module will increase the counter for Impressions Made (just like the regular mod_banners module), and it will register any clicked banner (in the Banner component under the column Clicks)
