        This is used to navigate through the xml/html document.
        Every xml/html object is represented by a python class
        instance that inherits from Root.

        The method sail is used to return an iterator
        for these objects.

        Example:
        data = '<a> <b> </b> </a>'

        html = Html()
        dom = html.feed(data)

        for ind in dom.sail():
            print type(ind),',', ind.name

        It would output.

        <class 'ehp.Root'> , a
        <class 'ehp.Root'> , b
