1) Splited FindLV into original find LV and a new class to find The TreeItem with maximum contrast agent Volume
2) Used default parameters to teh call of focusSegmentFromSelection, to handel the case of automatic segmentation, where no user defined name is given to the segmentation
3) Removed the bug were the segmentation result were attached to the selected treeItem in the list
4) Removed the bug where image processing performed on shrunk images instead of full size images.
