Classes derived from openwns.node.NoRadio cannot be instantiated any more

[Obaid Mushtaq]

After the introduction of the abstract "setChannelModel" method to scenarios.interfaces.INode, no class derived from openwns.node.NoRadio (which in turn is derived from scenarios.interfaces.INode) can be instantiated (e.g., ip.VirtualARP.VirtualARPServer) because the "setChannelModel" is not implemented in NoRadio (or in ip.VirtualARP.VirtualARPServer).

It could be fixed by adding this method to NoRadio (similar to the other methods implemented there):
 def setChannelModel(self):
        assert False, "This node is not a mobile radio node"

This is the error you get when trying to instantiate the ip.VirtualARP.VirtualARPServer:

PyConfig says:
Traceback (most recent call last):
  File "config_ITU.py", line 337, in <module>
    varp = VirtualARPServer("vARP", "WIMAXRAN")

This happens for example in the wimac-tests/configIMTA system tests.
