*
* A complex wrapper class that splits complex input image in two real-type
* subimages containing real and imaginary parts, that are interpolated using
* the standard itkBSplineInterpolateImageFunction. The same requirements apply
* for this class: Set spline order before setting the input image!
* Derivative support is currently not implemented
*
* This implementation was taken from the Insight Journal paper:
