/** \class StimulateImageIO
*
* \brief ImageIO class for reading SDT/SPR (Stimulate) images
* This format is similar to a MetaImageIO file:
* The user should specify the .spr file (not the data file : .sdt)
*
* This is based on the notes from:
*
* https://www.cmrr.umn.edu/stimulate/stimUsersGuide/node57.html
*
* It has been tested on:
*
* ftp://ftp.cmrr.umn.edu/pub/stimulate/data/
*
* \warning Beware of the scalar range of some files (See GetDisplayRange).
