[ns] assigning IP address to nodes

[Sidney Doria]

The best of NS-2 is its flexibility. If you didn't find a trivial
solution to assign a simple IP to a node, you can add a new attribute
to an inherited class of node. You can simply bind this new attribute
in your TCL script and assign what IP you want on the node you want.

The new atrribute can be of type nsaddr_t (IP address).

Hope to be useful,
