/** \class EquivalenceRelabeler
*
* This class is part of the set of watershed segmentation component objects.
* It is an image-to-image filter that relabels its input according to a set of
* equivalencies defined in a table. The filter is used in
* itk::WatershedImageFilter, for example, to relabel a segmented image
* at different hierarchies in the merge tree (see itk::WatershedImageFilter
* for documentation on terminology). It simply takes its input and changes
* any values found in the equivalency table.
*
* \par Inputs
* There are two inputs to this filter, an unsigned long itk::Image of
* arbitrary dimension, and an itk::EquivalencyTable. The input
* image is the image to be relabeled and copied to the output, and the
* EquivalencyTable identifies how to relabel the values.
*
* \par Output
* The output of this filter is the relabeled unsigned long itk::Image of same
* dimension and size as the input.
*
* \ingroup WatershedSegmentation
* \sa itk::WatershedImageFilter
* \sa EquivalencyTable */
