RoutingTableParser: temporary code to assist translating .irt to IPv4NetworkConfigurator XML
tmp: configurator: added some ideas
note about configurator problems

1. wireless router 192.168.0.1 conflicts with hosts on the wlan even
   though we didn't specify what address they should get
2. this conflict occurs even if the hosts interfaces don't need to be
   assigned addresses at all (i.e. are to be left alone)
problem with MPLS examples: configurator doesn't configure dynamically created nodes!

So LSR2 remains unconfigured after scenarioManager recreates it at t=4s
