    // input vertices.  This constructor accepts ownership of the input arrays
    // and will delete them during destruction.  The underlying triangle

    // constructor accepts ownership of the input function array, but does
    // not delete the triangle network on destruction.  The idea is that the
    // network was shared, either from an explicitly created one by the
    // application or from one created by another interpolator.
