Load treetop grammar only once. Save some time parsing multiple archetypes.
Use C_PRIMITIVE_OBJECT as wrapper to C_PRIMITIVE.
This add path and rm_type_name attributes for leaf objects - values.
Methods of C_PRIMITIVE are available directly from C_PRIMITIVE_OBJECT
(using method_missing). So no need to write C_PRIMITIVE_OBJECT.item
No changes to tests, they passes.
