=Introduction=

The term "structure set" is used in RT to denote a set of structures (labels) which are attached to an image.  
The goal of this project is to improve Slicer so it can handle overlapping structures.  
The following is a rough list of required functionality:

# Identify structureset images at load time
# Load structureset images
# Display overlapping contours in structure set
# Editor can switch between labelmap and structureset representation
# Modify editor GUI to make easier selecting current structure
# Save structureset images

=Notes=

* Identifying structureset images
** For now, I just assume that any vector image is a structureset image

* Loading structureset images
** Images, when loaded, are sent to vtkMRMLVolumeArchetypeStorageNode::ReadData(), which decides whether the file has a scalar or vector image
** The type of the MRML node created is vtkMRMLVectorVolumeNode
** Ref: Libs/MRML/Core/vtkMRMLVolumeArchetypeStorageNode.cxx
** A vtkMRMLVectorVolumeDisplayNode is attached to the storage node

* Displaying overlapping contours
