27 -=== Operations: ===
28 -
29 - - remove selected nodes from a connectivity, results in a new connectivity containing only the nodes that were not selected;
30 -
31 - - remove unselected nodes from a connectivity, results in a new connectivity containing only the selected nodes;
32 -
33 - - remove unselected edges, results in a new connectivity with the same number of regions but without the edges of unselected regions;
