 * \brief A 802.11 Channel
 *
 * This class works in tandem with the ns3::WifiPhy class. If you want to
 * provide a new Wifi PHY layer, you have to subclass both ns3::WifiChannel 
 * and ns3::WifiPhy.
 *
 * Typically, MyWifiChannel will define a Send method whose job is to distribute
 * packets from a MyWifiPhy source to a set of MyWifiPhy destinations. MyWifiPhy
 * also typically defines a Receive method which is invoked by MyWifiPhy.
