Renders the breadcrumbs in HTML tags.  If no options were
 provided on initialization, it uses defaults.

 @option @options [String] :outer ("ol") The outer tag element
   to use.
 @option @options [String] :inner ("li") The inner tag element
   to use.
 @option @options [Hash] :outer_options (nil) The outer tag
   element attributes to use.  Things like `class="some-class"`
   are best placed here.
 @option @options [Hash] :inner_options (nil) The inner tag
   element attributes to use.  Things like `class="some-class"`
   are best placed here.
 @return [String]
