BiGauss Histogram modelling (on the ventricles image):
Observation is that the "With Ratio" variant executes much faster than "Without Ratio" variant.
But then on this particular sample  the second one seems to have much better result.

Bimodal Gauss WITH Ratio
Bimodal Gauss (without Ratio)

BiGauss Histogram (without ratio) modelling:  Added the progress bar.
Improved Automatic DICOM loading function (does not require user input). Now function may be supplied with the file folder name. Before it required only the image file name of the actual dicom file.
FireVoxel Build 209 is released.

 1. Fixed the "IM file crash problem" (equal sign was missing):  an appropriate error message would be displayed now.
2. IVIM segmented model:
a) added parameter "Large B-value start" with the default value=200.  User can now change that value.
b) Increased the allowed ranges for Dp=[0,1],  Dt=[0,0.01]
IVIM basic model:
 Increased the allowed ranges for Dp=[0,1],  Dt=[0,0.01]
3. On Mouse Move - Display voxel information:  fixed a defect when the Active Layer is disabled, so moving the mouse did not produce any information in the status line.
Now if the Active is disabled, we choose the First enabled layer to display the voxel info.
4. Synchronize Multiprojection Cursor (mode=ON) functionality:  if there is a single View\Projection of the volume is visible the Crosshair cursor would not be visible.

5.  BiCal on Sodium images: fixed the defect when iterations of BiCal were producing a "better" result. This was due to the custom scheme of processing the REAL images, when internally they were converted to the 15 bit images and this was conflicting with the internal truncation
