Corrected the defect for "Save File" operations of any kind:  checking the overwrite of the existing file and warning the user.
RoiStat3D\RoiStat4D dialog:  when the volume without raster or vector ROIs is chosen, temporarily create a whole volume ROI and perform the measurement on it.

Implemented Non-uniformity layer measurement (Volume+2 blob layers) function feature:  for each slice number of blobs is measured and difference reported if any.  This helps to quickly find the slices where mistakes are made.

FireVoxel Build 185 is released.
CERENE GFR processing:  When any of the model calculations are activated, the Concentration Conversion dialog box pops up.   By default concentration Method is FWTE.  The TR and Flip angle are entered from DICOM header.  User needs to enter tissue T1 (sec).  AIF (blood) T1 is fixed at the moment and = 1.664 sec.

FireVoxel Build 184 is released.

1. Dialog RoiStats4D:  expanded and corrected functionality so that Raster and Vector ROI could be mixed together. Crash defect on PET-4D is corrected.
2. User Options dialog box: restored proper functioning of the Temp Directory browse button.
3. Removed the "MIDAS-Save" relater options from the User Options dialog box.
4.Upon FireVoxel start, program checks if the "Temporary File folder" specified in User Options configuration file is present.  If it is not present, Temporary file folder is created at default location: ApplicationDirectory:\Temp.
If the above fails, user is advised to reinstall FireVoxel to a different folder or "Run as Administrator" and program terminates.
5. Provided additional system diagnostics when the parametric map files are written.
6. Dynamic Modelling functionlity: moved all the interfacing functions from the main GUI application down to the DLL. This is in preparation to FirevoxelDynamicModellingCurve.exe command line module.
7. NIFTI  Float32 subtype:  enabled the loading.

8. Dialog RoiStats4D: changed the text of the “automatic retile” checkbox.
Dialog RoiStats4D:  expanded and corrected functionality so that Raster and Vector ROI could be mixed together. Crash defect on PET-4D is corrected.

NIFTI  Float32 subtype:  enabled the loading.
AutoFocus registration with the initial transform: restored to working condition.
Fixed the polynomial transform reslicing problem.
VTF file format read: Added the diagnostic to identify if user tries to load the old VTF format which is no longer supported and displays the suggestion to the user.

Disabled Huffman compression of large REAL volumes with MaxVoxVal>1M, so for major
speed up in saving and loading.
Incorporated support for ANALYZE 32-bit float files.
