'Construct a `Card` object from a (raw) string. It will pad the string
if it is not the length of a card image (80 columns).  If the card
image is longer than 80 columns, assume it contains ``CONTINUE``
card(s).'

def fromstring(cls, image):

    card = cls()
    card._image = _pad(image)
    card._verified = False
