/** \class ImageDuplicator
* \brief This helper class create an image which is perfect copy of the input image.
*
* This class is NOT a filter. Although it has an API similar to a filter, this class
* is not intended to be used in a pipeline. Instead, the typical use will be like
* it is illustrated in the following code:
*
* medianFilter->Update();
* ImageType::Pointer image = medianFilter->GetOutput();
* typedef ImageDuplicator< ImageType > DuplicatorType;
* DuplicatorType::Pointer duplicator = DuplicatorType::New();
* duplicator->SetInput();
* duplicator->Update();
* ImageType::Pointer clonedImage = duplicator->GetOutput();
*
* Note that the Update() method must be called explicitly in the filter
* that provides the input to the ImageDuplicator object. This is needed
* because the ImageDuplicator is not a pipeline filter.
*
