This datatype specifies how to measure along a curve

    PK_measure_distance_c           The measurement is an arc length distance.
    PK_measure_distance_ratio_c     The measurement is the ratio of a distance
                                    measured along the arc to the total arc
                                    length.
    PK_measure_chord_c              The measurement is a distance measured
                                    along the chord formed by joining the start
                                    and end points of the curve by a straight
                                    line.
    PK_measure_chord_ratio_c        Let B be the total length of the chord from
                                    the start point to the end point of the
                                    curve, and let A be the distance measured
                                    along the chord from the start point of the
                                    curve to any point on the chord. The
                                    measurement is the ratio A/B.
    PK_measure_2_chords_ratio_c     Let P be any point on the curve. Let A be
                                    the length of the chord from the start
                                    point of the curve to P, and let B be the
                                    length of the chord from P to the end
                                    point of the curve. The measurement is the
                                    ratio A / ( A + B ).
