MedicalViewerSeriesStack Class

This class is used for the output of the MedicalViewerSeriesManager.Sort method, which holds a sorted stack. Each image in the stack is sorted based on its actual real world position so it is displayed correctly. This also makes it easier for the 3D toolkit to create an accurate 3D object.
