   Purpose : this function is core funtion of this Navigation class. It is used to make links level_1,level_2,level_3
   Some links need extra parameters
   append them here but first set them in their methods
   e.g.
     public function set_group_id($group_id){

     }
     public function get_group_id() {

     }
   Scope : public
   @param - it needs no direct input
   @return - it sets class variables level_1,level_2,level_3 which can be used further.
