/**
* \class SparseImage
*
* \brief This class implements a storage type for sparse image data.
*
* \par
* This class is derived from the Image class. It uses the base class image
* data for storing pointers to variables of type TNode. The node type must
* have a member variable m_Index. The node data is
* stored using the SparseFieldLayer and ObjectStore classes to allow
* sequential list access to the nodes. This functionality is used in filter
* classes that process the SparseImage class such as
* FiniteDifferenceSparseImageFilter.
*
* \par
* This class provides the method AddNode which allocates a node variable,
* associates it with the image pixel index (sets m_Index in the node variable)
* and returns the pointer to the node variable. It is suggested that the user
* call the FillBuffer method to initialize the image to null pointers before
* any calls to AddNode. This would allow the user later to distinguish between
* valid and non-valid pixels.
*
