Images are sorted in Normalizer, but Labelmap are not

return fillSegmentation(segmentation, inputLabelmaps3D, userOptions);

Here the assumption is that after creating the Segmentation object, the references are still orderd like the images and the labelmaps. However, Normalizer sorts the images by physical position, resulting in mixing of the labelmaps in the stack.

ok, sorry, seems to be sorted out in #154

I think the problem is really in the fillSegmentation method that assumes same ordering as in segmentation object. The inputLabelmaps3D object does not have enough information, as this depends on the ordering of the images in the viewer. A solution would be to provide a map that maps from the labelmap indices to the referenced SOPInstanceUIDs, and the let fillSegmentation sort it out.
