Hi,

In an undirected graph, we create an undirected edge:

add_edge(a, b, g);

We get the reverse of that edge:

edge(b, a, g);

Now, are these two edges the same or different? vIf I compare them 
with the == operator, they are equal, but they have different source 
and target vertexes.

Can I count on this behavior?  Will it stick?  I'm asking because I 
couldn't find it in the documentation.

Please find attached my unit test.  On Debian Jessie, I'm compiling it 
with:

g++ test.cc -l boost_test_exec_monitor -l boost_unit_test_framework -o 
test

Thanks & best,
Irek
