[ndnSIM] [EXT] help about getting all the node out faces

[Junxiao Shi]

Hi Sofia

The FIB nexthop list only contains the routes added to the FIB.
If the routing helper is configured to insert only the shortest route,
you'll see only one nexthop in the FIB nexthop list.
To see multiple nexthops, you need to configure the routing helper to
insert multiple routes.

Yours, Junxiao
