+  <Description>
+    This function returns the edge connectivity of <A>digraph</A>.<P/> Edge Connectivity refers to the size of a minimum cut of the graph, 
+    which, for digraphs, refers to set of edges needed to be removed to ensure the graph is no longer Strongly Connected. That is, there exists two 
+    vertices, <A>A</A> and <A>B</A>, for which a path from <A>A</A> to <A>B</A> does not exist.
+
+    It makes use of the <C>DigraphMaximumFlow(<A>digraph</A>)</C> function, by constructing an edge-weighted Digraph
+    with edge weights of 1, then using the Max-flow min-cut theorem to determine the size of the minimum cut.<P/>
