#351 The docstring of Reader class is wrong

[Takeshi KOMIYA]

It seems the docstring of Reader class is wrong. There are no longer scan() method.

class Reader(Component):

    """
    Abstract base class for docutils Readers.

    Each reader module or package must export a subclass also called 'Reader'.

    The two steps of a Reader's responsibility are `scan()` and
    `parse()`.  Call `read()` to process a document.
    """

I don't know parse() is a responsibility of Reader. But it should be updated.
