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.)
