Support for class docstring

[Mengda-Li]

Can you add support for generating class docstring when class is detected (rather than def) like

class Photo(ndarray):
    """
    Array with associated photographic information.

    ...

    Attributes
    ----------
    exposure : float
        Exposure in seconds.

    Methods
    -------
    colorspace(c='rgb')
        Represent the photo in the given colorspace.
    gamma(n=1.0)
        Change the photo's gamma exposure.

    """

?
At least it is not supported for numpy style for the moment.
