   This is a modified version of the sample code provided with the TinyGPS++ library that
   demonstrates the normal use of a TinyGPS++ (TinyGPSPlus) object. It requires the use of
   SoftwareSerial, and assumes that a 9600 baud serial GPS device is connected to
   CubeCell Plus pins RX2(rx) and TX2(tx). It has been extended to display a subset of
   data on the CubeCell Plus display.
