ImageS4IterC<class Data1C,class Data2C,class Data3C,class Data4C>
Pointer based image iterator for image pairs.
include	"amma/ImageS4Iter.hh"
User Level:	Default
Library:	Image
Example:	exIter.cc
Section:	Image.Indexing.Iterators
In Scope:	std

Comments:
NB. This does NOT hold a refrence to any of the images!

Allows FAST iteration over a pair of images. It is intended for implementing image processing operations which require access to a pixel in two images.

Note that the two images do not need to be of the same type.
