Adds a control point to the terrace-forming curve.
@param value The value of the control point to add.
@pre No two control points have the same value.
@throw new ExceptionInvalidParam An invalid parameter was
specified; see the preconditions for more information.
Two or more control points define the terrace-forming curve. The
start of this curve has a slope of zero; its slope then smoothly
increases. At the control points, its slope resets to zero.
It does not matter which order these points are added.
