docs: Create a RedditContentObject function mapped to a BaseReddit function.
  
      The BaseReddit classes define the majority of the API's functions. The
      first argument for many of these functions is the RedditContentObject that
      they operate on. This factory returns functions appropriate to be called on
      a RedditContent object that maps to the corresponding BaseReddit function.
