   --returnparameterfile <std::string>
     Filename in which to write simple return parameters (int, float,
     int-vector, etc.) as opposed to bulk return parameters (image,
     geometry, transform, measurement, table).

   --processinformationaddress <std::string>
     Address of a structure to store process information (progress, abort,
     etc.). (default: 0)

     Produce xml description of command line arguments (default: 0)

     Echo the command line arguments (default: 0)

     debug (default: 0)

   --elecOrder <double>
     order for the calculation of Electrostatic energy. (default: 2)

   --weight <double>
     Weight for single shell term, 1-weight for mutiple shell term.
     (default: 0.5)

     Criteria Type. (default: DISTANCE)

   --tessOrder <int>
     Tessellation order for the fine orientations. (default: 7)

   --initialOrientations <std::string>
     A given orientations for an intialization.

   --fineOrientations <std::string>
     A given fine orientations. It overrides --tessOrder

   --numberOfSamples <std::vector<int>>
     number of samples in single/multiple shells.

   --,  --ignore_rest
     Ignores the rest of the labeled arguments following this flag.

     Displays version information and exits.

   -h,  --help
     Displays usage information and exits.

     (required)  Output orientation file(s), single shell or multiple
