Return True if the graph is semiconnected, False otherwise.
A graph is semiconnected if, and only if, for any pair of nodes, either one is reachable from the other, or they are mutually reachable.
G : NetworkX graph
A directed graph.
semiconnected : bool
True if the graph is semiconnected, False otherwise.
If the input graph is not directed.
If the graph is empty.
