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.
