createMXCubicAlongArc MethodStatic

Create an MX Cubic whose nominal length is close to along the curve. This is y= m*x^3 with

• m is 1/ (6RL1)
  • 1/(6RL) is the leading term of the sine series.
• L1 is an along-the-x-axis distance that is slightly LESS THAN the nominal length
• x is axis position that is slightly LESS than nominal distance along
• L1, x use the approximation `x = s * ( 1 - s^4/ (40 R R L L))
