   =item breadcrumbs
   
   Compiles the previously registered breadcrumbs into an series of links.
   FAQ and BUG links will be placed on the left side of the table if they
   are defined for the last registered breadcrumb.  
   Additionally supports a 'component', which will be displayed on the
   right side of the table (without a link).
   A link to help for the component will be included if one is specified.
   
   All inputs can be undef without problems.
   
   Inputs: $color (the background color of the table returned),
           $component (the large text on the right side of the table),
           $component_help
           $function (role to get colors from)
           $domain   (domian of role)
