  ENH: Copying LesionSegmentation to LesionSegmentationNIST.
ENH: Copying LesionSegmentation to LesionSegmentationNIST.

This is in preparation for customization for a specific project.
ENH: Changing the seed parameter to accept a csv file.
ENH: Adding a skeleton interface for OutputAIM.

This included a skeleton filter and the addition of a command-line
parameter to output in AIM's XML format for lesion segmentations. This
format is a slice-by-slice contour format.
WIP: Work at the beach.
BUG: Working around IO Factory registration to allow mha output.
WIP: Work on moving the contours into the proper space.
WIP: Lots of work. Feels almost done
WIP: Removing couts and adding documentation to finish up the module.
ENH: Updateing the contour extractor header.

ITKv4 changed an include path on itk_hash_map
ENH: Adding a new module for further work with NIST.

This new module differs from LesionSegmentation in that it takes a new
parameter on the command line to indicate whether the seed point(s) and
ROI are in physical space or image index space.
BUG: Udating LesionSegmentationQIBench to match LesionSegmentationNIST.
ENH: Adding offsetting from origin for improperly specified coordinates.
BUG: Adding a missing id field from the aim file.
