int a;
int s = network.nodes.size();
for (a=0;a<s;a++)

stream << *(network.nodes[a]);
}
}
ostream& operator<< (ostream& stream, const Node& node)
{
stream << node.label ;
}
int main()
{
Node * n = new Node("W");
cout << *n ; // IT WORKS
cout << *n <<endl; // IT WORKS
Network * x = new Network();
x->addNode("A");
