Program 
 defines the Digraph interface.
The Digraph interface extends the Graph interface
defined in Program 
.
   
Program: Digraph interface.
The Digraph interface adds the following operations
which apply only to directed graphs
to the inherited interface:
- IsStronglyConnected
 - 
	This bool-valued property is true
	if the directed graph is strongly connected.
	Strong connectedness is discussed in Section 
.
     - TopologicalOrderTraversal
 - 
	A topological sort is an ordering of the nodes of a directed graph.
	This traversal visits the nodes of a directed graph in the order
	specified by a topological sort.
