The computation exitSuccess is equivalent to exitWith ExitSuccess, It terminates the program successfully.

Given source nodes n1,n2,... find all target nodes m1,m2, such that for all j, there are edges n_i --l_ij--> m_j for all i. Return these edges as a map from target notes to a list of edges. We assume the graph is reflexive-transitive.
