• Implement tornado_json.gen.coroutine
  • As a fix for #59 , a custom wrapper for the tornado.gen.coroutine wrapper has been implemented. This was necessary as we lose the original argspec through it because the wrapper simply has (*args, **kwargs) as its signature. Here, we annotate the original argspec as an attribute to the wrapper so it can be referenced later by Tornado-JSON when generating routes.
