t.p.nmea : module documentation

Classes for working with NMEA 0183 sentence producing devices. This standard is generally just called "NMEA", which is actually the name of the body that produces the standard, not the standard itself..

For more information, read the blog post on NMEA by ESR (the gpsd maintainer) at http://esr.ibiblio.org/?p=801. Unfortunately, official specifications on NMEA 0183 are only available at a cost.

More information can be found on the Wikipedia page: https://en.wikipedia.org/wiki/NMEA_0183.

The official standard may be obtained through the NMEA's website: http://www.nmea.org/content/nmea_standards/nmea_0183_v_410.asp.
