[Insight-developers] periodic boundary condition

[Joshua Cates]

Hi,

I am writing a periodic boundary condition object for the neighborhood 
iterators.  This is class which returns out-of-bounds values 
by "wrapping around" the image.

I'm looking for opinions on the following issue.  A neighborhood iterator 
will only invoke the boundary condition if it finds itself touching an 
edge of the Image::BufferedRegion.
