    A decorator that performs %-substitution on an object's docstring.

    This decorator should be robust even if ``obj.__doc__`` is None (for
    example, if -OO was passed to the interpreter).

    Usage: construct a docstring.Substitution with a sequence or dictionary
    suitable for performing substitution; then decorate a suitable function
    with the constructed object, e.g.::

        sub_author_name = Substitution(author='Jason')

        @sub_author_name
        def some_function(x):
            "%(author)s wrote this function"

        # note that some_function.__doc__ is now "Jason wrote this function"

    One can also use positional arguments::

        sub_first_last_names = Substitution('Edgar Allen', 'Poe')

        @sub_first_last_names
        def some_function(x):
            "%s %s wrote the Raven"

    A `.Substitution` with two additional features:

    - Substitutions of the form ``%(classname:kwdoc)s`` (ending with the
      literal ":kwdoc" suffix) trigger lookup of an Artist subclass with the
      given *classname*, and are substituted with the `.kwdoc` of that class.
    - Decorating a class triggers substitution both on the class docstring and
      on the class' ``__init__`` docstring (which is a commonly required
      pattern for Artist subclasses).
