* This class defines the inner product operation between an

* operator() method is overloaded to support various types of
* neighborhoods as well as inner products with slices of
* neighborhoods. The second template parameter allows you to set the
* value type of the operator. The third templage parameter allows you
* to set the value type used as the return type of the inner product
* calculation. The operator value type defaults to the image pixel
* type and the output value type defaults to the operator type.
