/** \class SpatialFunction
* \brief N-dimensional spatial function class
*
* itk::SpatialFunction provides the ability to define functions that can
* be evaluated at an arbitrary point in space (physical or otherwise). The return
* type is specified by the derived class, and the input to the function
* is an n-dimensional itk::Point.
*
* Although itk::ImageFunction and itk::SpatialFunction are quite similar,
* itk::SpatialFunction derived classes exist without reference to an Image
* type.
*
* SpatialFunction is templated over output type (the data type
* returned by an evaluate() call) and dimensionality.
*
* \ingroup SpatialFunctions
