   =pod
   
   =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)
           $menulink (boolean, controls whether to include a link to /adm/menu)
   
   Returns a string containing breadcrumbs for the current page.
   
   =item clear_breadcrumbs
   
   Clears the previously stored breadcrumbs.
   
   =item add_breadcrumb
   
   Pushes a breadcrumb on the stack of crumbs.
   
   input: $breadcrumb, a hash reference.  The keys 'href','title', and 'text'
   are required.  If present the keys 'faq' and 'bug' will be used to provide
   links to the FAQ and bug sites.
