/*
This sample demonstrates TinyGPS++'s capacity for extracting custom
fields from any NMEA sentence. TinyGPS++ has built-in facilities for
extracting latitude, longitude, altitude, etc., from the $GPGLL and
extracting latitude, longitude, altitude, etc., from the $GPGGA and
$GPRMC sentences. But with the TinyGPSCustom type, you can extract
other NMEA fields, even from non-standard NMEA sentences.
