LengthToS() converts a physical length along the trajectory to the parameter s used in Pos, Vel and Acc.
This is used because in cases with large rotations the parameter s does NOT correspond to the lineair length along the trajectory. User should be sure that the lineair distance travelled by this path object is NOT zero, when using this method ! (e.g. the case of only rotational change) throws Error_MotionPlanning_Not_Applicable if used on composed path objects.
