/** \class PointSetToSpatialObjectDemonsRegistration
* \brief Implementation of Demons Registration between a PointSet and a SpatialObject
*
* The simplest case of Demons registration suggested by P. Thirion in his
* paper[1] is defined by a Model and Scene. The Model should be able to
* respond to the queries of whether a point is inside or outside of the object
* of interest, while the Scene provides a number of points (the Demons) with
* vector indicating the direction of inside-outside of the equivalent object
* of interest. In this implementation, the Scene is represented by an
* itk::PointSet that has Vectors as PixelData. These vectors should be
* provided by the user of this class and must be pointing outside of the
* object of interest. The Model is naturally represented by a
* itk::SpatialObject since its interface responds to the IsInside() method.
*
* This class is intended to be derived in order to define the method that will
* update the transform. Such method will be specific for the particular type of
* transform used.
