// usage: cgraph type
//
// Copy a graph of specified type from stdin to stdout.
// Why you ask? To test input and output operators, of course.
// We also do an assignment in between input and output,
// in order to test the assignment operator.
//
// The allowed values of type are graph, wgraph,
// digraph, wdigraph, flograph, wflograph.
