FireVoxel Build 246 is released.

IVIM free (non-segmented) model:  implemented an additional user control fMax which specifies the range of values for the optimization.

Changed the design of composite  "Brain EdgeWave\N3" segmentation function.  NU layer is now popped up and the original layer is disabled.

Fixed some defects with loading the 4-timepoint PET MIDAS file.
