Build 392 is released.

 1. Fixed: Background voxels in NII are assigned value which is Not A Number (NAN = i.e. sequence of bytesthat have no meaning as a floating point number). 

So FireVoxels loads those voxels as VOID.  User has an option to save it back to NII, than FVX shows the dialog "Replace VOID voxels with X".

2. Histogram segmentation:  removed PVV and Zigalga methods from the User interface. They are still used in legacy workflows.

3. Integrated the Gaussian Mixture Models c++ code.  Exposed the GMM model as the HIstogram Segmentation.

4. Removed the PVV and ZIGALGA methods from User Interface.

5. Fixed the crash: Loading a {ANALYZE,IM} file, VROI, Crop.  This was due to the missing Dynamic Coordinates.

6.  AutoFocus4D dialog box. Performed adjustments, removed the Ensemble algorithm option and corresponding fields.

7. Layer Control dialog: "Remove layers" operation: added a check when all layers are unmarked to prevent crash.

8.  Transform>Rotate Orthogonal  :  now transforms all the layers of the Entity.

9.  Transform>Rotate Orthogonal  :  updates the orientation of the new volume correctly..

9. VROI on multilayer entity:  automatically selects the layer with MaxT for use in VROI.

10. Enclose connected component by the VROI now automatically generates the VROI name.
