Image3IterC<class Data1C,class Data2C,class Data3C>
Pointer based image iterator for image triples.
include	"amma/Image3Iter.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 three images. It is intended for implementing image processing operations which require access to the same pixel in three equal sized images.

Note that the input and output images do not need to be of the same type.
