* \class AnchorErodeDilateLine
* \brief class to implement erosions and dilations using anchor
* methods. This is the base class that must be instantiated with
* appropriate definitions of greater, less and so on. There is
* special code for cases where the structuring element is bigger than
* the image size that aren't particularly anchor related, but use the
* same data structures. Hopefully these sections occupy a very minor
* proportion of the time.
