NMEA 0183 implementation

Maintainer: Bob Ippolito

The following NMEA 0183 sentences are currently understood:

   GPGGA (fix)
   GPGLL (position)
   GPRMC (position and time)
   GPGSA (active satellites)

The following NMEA 0183 sentences require implementation:

   None really, the others aren't generally useful or implemented in most devices anyhow

Other desired features:

   - A NMEA 0183 producer to emulate GPS devices (?)

Class	InvalidSentence	Undocumented
Class	InvalidChecksum	Undocumented
Class	NMEAReceiver	This parses most common NMEA-0183 messages, presumably from a serial GPS device at 4800 bps.
