Developed a function, when given a 4D volume and an ROI (3D or 4D),   FVX advances to timepoint where amount of information (or entropy) over the given ROI is maximum. 

This is an extremely valuable function for all 4D registrations.  It allows user to automatically select an "Anchor" point for 4D registration.

Prior to this development, every individual workflow required an individually crafted recommendation which timepoint to use as an "anchor" for the registration.

Re-implementing the frequent {VolumeCropSlice, VolumeCropTimepoint} operations which are frequently used in processing.  Idea is to perform it through copying compressed blocks, instead of VolumeGetBox-VolumeSetBox sequence that require   Decompress\Compress.

Pair of this function is used extensively in Registrations and in over 70 locations inside the FireVoxel.
