      Check whether a certain path is inside a known type of repository and
      returns an instance representing it. May also check for a certain type
      instead of detecting the type of repository.
  
      .. deprecated:: 0.16
         Use the pattern `Dataset(get_dataset_root(path)).repo` instead. This
         function will be removed in a future release.
  
      Parameters
      ----------
      path: str
        path to check; default: current working directory
      class_: class
        if given, check whether path is inside a repository, that can be
        represented as an instance of the passed class.
  
      Raises
      ------
      RuntimeError, in case cwd is not inside a known repository.
