/* FIXME: THE CLEANUP FUNCTION IS BUGGY BECAUSE THERE'S A RACE CONDITION BETWEEN LOADING ADS AND CHECKING THEM! Cleanup function is only going to work if we load the ads before dom ready*/
/*FIXME: or is it actually because it can't check the pattern inside an iframe?*/

// Once the ads have been rendered, we need to clean up the page,
// as not all ad spaces will have ads targeted to them, and we
// still have a few 'holes' in the page. It will hide any empty
// ad spaces, hide ad groups that have no visible spaces.
// We can pass in a couple of options; one being a regex we can 
// use to find placeholder content in empty ad spaces; Options
// exist to change the `id` attributes on ad spaces
// giving us more freedom. All options have defaults. If a function
// is passed as a second parameter, if will be called upon completion.
