Remarks
Use the PiecewiseLinearCurve class to represent a curve or function that looks like
a broken line. It is most commonly used for linear interpolation of tabulated data that represents a continuous function.
On each interval between two data points, the curve is approximated by a straight line between the data points.
Piecewise linear curves inherit from PiecewiseCurve.
