original_docstring: Initialize logging for this run.
  
          After execution of this method, the log directory structure was
          created, code was copied and commited if desired, and some basic system
          information has been logged. Subsequent use of loggers from
          log.get_logger will result in log files written to the run directory.
  
          Parameters
          ----------
          log_dir : str
  	    Create new run directory under this directory.
          run_dir : str
  	    Resume in existing run directory.
          code_root : str
  	    Path to where the code lives. py and yaml files will be copied into
              run directory.
          postfix : str
  	    Identifier appended to run directory if non-existent else to latest
              eval directory.
          log_level : str
  	    Default log level for loggers.
          git : bool
  	    If True, put code into tagged commit.
