code: def load_history(self, model, skip={"gh-pages"}):
          
          if self._history is None:
              self.build_branch_structure(model, skip)
          self._results = dict()
          all_commits = list(self._history["commits"])
          for commit in all_commits:
              try:
                  self._results[commit] = self.manager.load(commit)
              except (IOError, NoResultFound) as err:
                  LOGGER.error("Could not load result '%s'.", commit)
                  LOGGER.debug("%s", str(err))
docs: Load the entire results history into memory.
  
          Could be a bad idea in a far future.
