Add a SpectrumPhy to a channel, so it can receive packets.
This method is used to attach a SpectrumPhy instance to a SpectrumChannel instance, so that the SpectrumPhy can receive packets sent on that channel. Note that a SpectrumPhy that only transmits (without receiving ever) does not need to be added to the channel.
This method is to be implemented by all classes inheriting from SpectrumChannel.

If any of those objects are chained together (e.g., multiple PropagationDelayModel objects), the base class of that object is responsible for ensuring that all models in the chain have AssignStreams recursively called.

Destructor implementation.
This method is called by Dispose() or by the Object's destructor, whichever comes first.
Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.
It is safe to call GetObject() from within this method.
Reimplemented from ns3::Object.
