[ITK] Compilation error when changing boundary condition

[Bill Lorensen]

I can reproduce your problem and I see the issue.
NeighborhoodInnerProduct operator()'s second argument is const
ConstNeighborhoodIterator< TImage >.
Notice that the boundary condition template parameter is not specified.

So, you cannot change the boundary condition when you use the
neighborhood inner product. This is design bug. I'll take a look at
how this could be redesigned.
