[Insight-developers] itkImageConstIteratorWithIndex.h

[Mark Foskey]

In itkImageConstIteratorWithIndex.h, both IsAtBegin() and IsAtEnd() 
return !m_Remaining.  It appears that

   it.GoToBegin();
   std::cout << it.IsAtBegin() << std::endl;

   it.GoToEnd();
   std::cout << it.IsAtEnd() << std::endl;

will both print 0.  Do we at least want to document this behavior?  I 
can imagine scenarios where you might want to test whether an iterator 
has been incremented since GoToBegin() was called, although I think 
they would be rare.
