[hpsdr] ghpsdr3 Communication Protocols

[Dave Larsen]

John Melton's current communication protocols are now available on
either the ghpsdr3 ( http://openhpsdr.org/wiki/index.php?title=Ghpsdr3 )
and the Athena  ( http://openhpsdr.org/wiki/index.php?title=ATHENA )
Wiki pages.  It can also be found in John's ghpsdr3 SVN under the 'doc'
directory.  

This is our first cross-platform multi-receiver protocol and is proposed
as the basis for future communication interface development.
