/** \class VectorAnisotropicDiffusionFunction
*
* This class implements a vector-valued version of
* AnisotropicDiffusionFunction. Typically in vector-valued diffusion, vector
* components are diffused independently of one another using a conductance
* term that is linked across the components. Refer to the the documentation of
* AnisotropicDiffusionFunction for an overview of anisotropic diffusion. The
* way that the conductance term is calculated is specific to the specific type
* of diffusion function.
*
* \par Data type requirements
* This filter was designed to process itk::Images of itk::Vector type. The code
* relies on various typedefs and overloaded operators defined in itk::Vector.
* It is perfectly reasonable, however, to apply this filter to images of other,
* user-defined types as long as the appropriate typedefs and operator overloads
* are in place. As a general rule, follow the example of itk::Vector in
* defining your data types.
