* \class MiniPipelineSeparableImageFilter
* \brief A separable filter for filter which are using radius
*
* This filter takes a non separable implementation of a neighborhood
* filter, and run it several times (one per dimension) to implement
* the same separable transform.
* This filter can be used with the filter for which the neighborhood is
* defined by the SetRadius() method, like the BoxImageFilter and its
* subcalsses.
