// NiBSplineBasisData contains an NiBSplineBasis for use in interpolation 
// of open, uniform B-Splines. This class is separate from NiBSplineData  
// because NiBSplineBasis caches its values internally so that subsequent  
// calls will save calculations. Since multiple NiBSplineInterpolators
// may have the same NiBSplineBasis, this value is encapsulated 
// in an NiObject container, allowing it to be cloned and streamed
// appropriately.
