location:
+ default $location = $name
+ default $index_files = undef
+ permit $www_root == undef &...: then we will create directory location reference with no root (nginx will inherits from server or http define
+ fixes error when declare 2 locations '/x' & '/x/'
+ permit raw location_cfg_prepend & location_cfg_append (we check .is_a? Hash before processing)
+ note: I tested only with vhost_location_directory!

vhost: add www_root & index_files
