     object: An object that inherits from class `spline'.

   DDeessccrriippttiioonn::

        Return the order of the object.  The order of a spline
        is the number of coefficients in each piece of the
        piecewise polynomial representation.  Thus a cubic
        spline has order 4.

        An integer vector of length 1.
