+  Controller Class,
+  by Gary P. Scavone, 2000
+
+  This object will accept control messages
+  from a variety of sources, such as a MIDI
+  port, scorefile, socket connection, or
+  pipe.  MIDI messages are retrieved with
+  the RtMidi class.  All other input sources
+  (scorefile, socket, or pipe) are assumed
+  to provide SKINI formatted messages.
+
+  For each call of getNextMessage(), the
+  active input devices are queried to see
+  if a new control message is available.
+  Only one message per call is returned, so
+  a subsequent call begins querying the
+  next available device "after" the previously
+  handled one.
+
+  This class is primarily for use in STK
+  main() event loops.
+
+  One of my original goals in creating this class
+  was to simplify the message acquisition process
+  by removing all threads.  If the windoze
+  select() function behaved just like the unix one,
+  that would have been possible.  Since it does not
+  (it can't be used to poll STDIN), I am using a 
+  thread to acquire messages from STDIN, which are
+  then sent via a socket connection to the message
+  socket server.  Perhaps in the future, I will be
+  able to simplify things.
