/*
* Breadcrumb navigation class
* Mick Sear
* http://www.ecreate.co.uk
*
* The key to using this is to decide on a $level for each page. (array, starting position 0)
* This determines where in the trail a link will be placed. So, I normally make the homepage level 0,
* then every page that can be accessed from the top level nav becomes level 1, and every page
* from that second level becomes level 2, and so on. When users return to a higher level (e.g. level 1)
* the surplus links are removed. Only one page can occupy a $level in the crumb trail.
* There might be several routes to a page. In which case, the trail will reflect the route that the
* user actually took to get to that page.

class Breadcrumb{
var $output;
var $crumbs = array();
var $location;
/*
* Constructor
*/
function Breadcrumb(){
if ($_SESSION['breadcrumb'] != null){
$this->crumbs = $_SESSION['breadcrumb'];
}
}
/*
* Add a crumb to the trail:
* @param $label - The string to display
* @param $url - The url underlying the label
* @param $level - The level of this link.
