CLASS
WhoiUam

DESCRIPTION
Driver for WHOI UAM ("Underwater Acoustic Modem"). 

Note that this class contains an instance of an ExternalMsgHandler.
This allows us to de-couple the specifics of reading and writing
messages (this class) from the way in which messages are actually
handled (the ExternalMsgHandler interface).
