Simple Point To Point Channel.
This class represents a very simple point to point channel. Think full duplex RS-232 or RS-422 with null modem and no handshaking. There is no multi-drop capability on this channel -- there can be a maximum of two point-to-point net devices connected.
There are two "wires" in the channel. The first device connected gets the [0] wire to transmit on. The second device gets the [1] wire. There is a state (IDLE, TRANSMITTING) associated with each wire.

ns3::PointToPointChannel::PointToPointChannel | ( | ) |
Create a PointToPointChannel.
By default, you get a channel with the name "PointToPoint Channel" that has zero transmission delay.
