    # Returns the Gravatar for the given user.

    # The +user+ is the user you want to get the gravatar for.
    #
    # Valid options:
    # *   +size+ The size (in pixels) for the returned gravatar.  The gravatar will be a square image using this
    #     value as both the width and height.  The default is 80 pixels.
    # *   +default+ The default image to return when no image is set. This can be nil, :mm, :identicon, :monsterid,
    #     :wavatar, or :retro.  The default is :identicon.
