* \brief Class to aggregate to a NetDevice if it supports MPI capability
*
* MpiInterface::ReceiveMessages () needs to send packets to a NetDevice
* Receive() method. Since each NetDevice's Receive() method is specific
* to the derived class, and since we do not know whether such a NetDevice
* is MPI-capable, we aggregate one of these objects to each MPI-capable
* device. In addition, we must hook up a NetDevice::Receive() method
* to the callback. So the two steps to enable MPI capability are to
* aggregate this object to a NetDevice, and to set the callback.
