Sokoloff model verified working on Brookhaven data.

For ALL  FireVoxel operations using the Vector ROIs as seeds:  new better logic is implemented.
For when a single seed is required and several seeds are present, Fvx requires a single seed to be
selected and warns otherwise.

Ensure correct functioning of the Anatomy-constrained (tube) IDIF function on the Brookhaven PET data.
In this example, two Macroseeds left and right are placed by User on the branches of the carotid artery.
Algorithm ran twice with identical (default) parameters.

Positioning of both corresponding ROIs are shown on orthogonal projections.

Testing latest Anatomy IDIF function on the PET case from  Brookhaven.  This (along with blood data) will be used to validate the IDIF function.
