itkFiniteDifferenceImageFilter IS actually wrapped.  The fact that
SetNumberOfIterations() is not accessible is due to a different
problem in the Wrapping system.  Wrapped methods "disappear" if child
classes have a different template signature.  I've filed a bug report
on this (with id 1398), please see:

In Marcelo's case:
itkFiniteDifferenceImageFilter has template signature <TInputImage,
TOutputImage> whereas itkPDEDeformableRegistrationFilter (child of
FiniteDifference and parent of Demons, he he) has template signature <
TFixedImage, TMovingImage, TDeformationField>.  The method is present
in the wrapped FiniteDifference, but has already disappeared from

I believe that Brad is The Only One that can fix this one.
