These changes allow NMEA data to be read via I2C on UBLOX compliant devices that support this capability, such as the LEA-6H based GPS shield from DFRobot. It adds a new init() function to the C code, and a new constructor to the C++ code. It also adds 5 new examples for C, C++, Javascript, Python, and Java. Signed-off-by: Jon Trulson <jtrulson@ics.com>
