InetWvIn supports multi-channel data. It is important to
distinguish the tick() methods, which return samples produced by
averaging across sample frames, from the tickFrame() methods,
which return references or pointers to multi-channel sample
frames.
distinguish the tick() method that computes a single frame (and
returns only the specified sample of a multi-channel frame) from
the overloaded one that takes an StkFrames object for
multi-channel and/or multi-frame data.
This class implements a socket server. When using the TCP
protocol, the server "listens" for a single remote connection
