add test main function for RTCMv3 parser
Fix argument list to RTCMv3 parser to add port number
Add ntrip port to the command line
Make the warning about the Kepler eqn not converging more useful
Make the output of the RTCM decoder less verbose
Add the ability from the RTCMv3 decoder to read from our own NTRIP client rather than the external binary
Add a python-coded ntrip client that spits its output to stdout; works as a drop-in replacement for the reference POSIX implementation
Change the NTRIP user agent string to be us rather than the POSIX reference implementation (which was there for testing purposes)
Add some comments to the NTRIP client explaining why we arent working with their length headers
