Compute information associated with a point on a nurbs curve. The point is specified with the input curve (inputCurve) and the parameter value (parameter), either in the curve domain or in the 0-1 domain (if turnOnPercentage is set to true.) The information available is: position, curve normal (normalized to length 1 in normalizedNormal), curve tangent normalized to length 1 in normalizedTangent), curvature radius (curvatureRadius) and the center of curvature (curvatureCenter.)
