class Timed:
    """
    A context manager which measures and optionally logs context run time.

:param msg: A message that describes the thing that is being measured
    :param threshold: Threshold, in seconds. When the context exceeds this
        threshold, a log will be made.
    :param log_mode: Control whether to log. Defaults to "threshold". Possible
        values include:
        "always" - Always log 'msg', even when 'threshold' is not reached.
        "threshold" - Log when context time exceeds 'threshold'.
        "skip" - Do not log. Context time and message are stored in the
            'output' and 'delta' attributes, respectively. Used to manually
            coalesce with other logs at the call site.

usage:

this call:
        ```

might produce this log:
