Module Ppx_log_syntax

ppx_log translates to code that references a module Ppx_log_syntax : Ppx_log_types.S expected to be in scope. Normally, this is provided by an actual log implementation, like Async_log. If the module isn't in scope, this library provides a stub implementation with an alert to direct users to the right place.
