ENH: Add support to read image position and orientation (patient) tags for images of modality NM when Image Type(0008,0008), Value 3, is RECON TOMO or RECON GATED TOMO.
ENH: Add a helper method to know whether a volume is a primary NM acquisition
ENH: Primary NM acquisitions are displayed using Black & White Inverse transfer function like PT acquisitions.
ENH: Window Level in primary NM acquisitions is treated the same way as PT volumes.
ENH: Add support to be able to fuse NM and CT volumes.
ENH: Enable the display of NM and CT fused volumes from the patient menu browser.
ENH:  Making Magic ROI to use the NM volume to define the region in NM-CT fusion.
BUG: The destructor of AbstractROIDataPrinter must be virtual.
ENH: Add units for primary NM studies
ENH: Print custom ROI data for NM and NM-CT volumes.
ENH: Add a new CLUT for PET and NM volumes based on the CLUT called "PET" from Osirix.
ENH: Set "PET Osirix" CLUT as default for PET and NM volumes when fused with CT volumes.
