AutoFocus Registration (3D and 4D):  substantially improved the design and implementation of the AutoFocus algorithm when the Target ROI is positioned close to the boundaries of the Volume.

Made additional corrections affecting the Gradient Measure (URAL), to always inflate Target ROI (internally and implicitly) by 1 voxel to account for the   vertice of the lattice vs.  center of the lattice representation of the gradients.

Both changes have resulted in much better registration in Liver DCDI case.

a) before registration on the mid-sagittal slice                               b) after registration
