title: How to add an item to magento breadcrumbs
body: <p>I want to display breadcrumbs while a use navigates my own module on the frontend of magento, the site already has the appropriate breadcrumb code in place thats used elsewhere as per standard magento breadcrumbs.</p>
  
  <p>What do I need to do in my module to specify the current breadcrumb path?</p>
  
  <p>I'd prefer to be able to do this programmatically rather than having to write something custom in the breadcrumbs phtml file</p>
