Description: Fits principal surfaces, the two-dimensional
        generalisation of the principal curves of Hastie and Stuetzle
        (1989) <doi:10.1080/01621459.1989.10478797>, and displays them
        as biplots in which each variable is read off the contour lines
        of its fitted surface coordinate function. Sample predictivity,
        the proportion of a sample's squared length that is
        reconstructed by the fitted surface, is reported as a
        per-sample diagnostic of how well the surface represents the
        data.
