New for ITK 5.0: IndexRange, ZeroBasedIndexRange, ImageRegionIndexRange

itk::Experimental::IndexRange template class

This is awesome.

@Niels_Dekker

for (const auto& index : indexRange)
{
  shapedImageNeighborhoodRange.SetLocation(index);

  for (PixelType neighbor : shapedImageNeighborhoodRange)
  {
    // Process neighbor pixel here... 
  }
}

So IndexRange makes it easier to interchange between “old-school” and range-based neighborhood iteration, and it also eases comparing both the performance and the result, for testing purposes.

How do you think a class would be designed to works on an itk::Image, but does not need to iterate over the neighborhood, i.e. *it is the pixel value?
