Comment 3 for bug 1271428

"Delete network" is supported in the network detail page now, so the required steps are now (1) click the network to be deleted and jump to the network detail page, (2) select "Delete Network" in the network detail page and (3) click the confirm dialog. The required steps has been simplified a lot.

If we support delete network in the network topology view, it seems better to use a pop-up window for a network as we do for servers, routers.
