* \class LevelSetNode
* \brief Represent a node in a level set.
*
* LevelSetNode is a simple templated class that represents a node
* or grid position of a level set. A group or collection of
* LevelSetNode can then be used to represents a narrowband or
* region of interest.
*
* LevelSetNode is templated over the data type and dimension of the
* level set.
*
* \ingroup LevelSetSegmentation
