/* this class used for splitting superpixels into subsuperpixels. 
 It is done simultaneously by all superpixels tpgethere. 
 input is the segmentation map and output is the distance map 
from each startpoint whithin each superpixeks for all superpixels
Class methods currently are implemented on cpu*/
