Re: nam problem with node

[Haobo Yu <haoboy@isi.edu>]

You have to use Simulator::node{} to create new nodes so that it appears
in nam trace file. If you want your own node class, also see
Simulator::node-config{} and how you can change these methods to include
your new node types. See ns manual chapter 17 for detail. 

I assume you were using 2.1b6 or current snapshot. If an earlier version,
you probably want to study how Simulator::node{} is written.
