+/*******************************************************************************************************
+  Program Operation - This is a simple program to test a GPS. It reads characters from the GPS using
+  software serial and sends them (echoes) to the IDE serial monitor. If your ever having problems with
+  a GPS (or just think you are) use this program first.
+
+  If you get no data displayed on the serial monitor, the most likely cause is that you have the receive
+  data pin into the Arduino (RX) pin connected incorrectly.
+
+  GPS baud rate set at 9600 baud, Serial monitor set at 115200 baud. If the data displayed on the serial
+  terminal appears to be random text with odd symbols its very likely you have the GPS serial baud rate
+  set incorrectly for the GPS.
+
+  Note that not all pins on all Arduinos will work with software serial, see here;
+
+  https://www.arduino.cc/en/Reference/softwareSerial
+
+  Serial monitor baud rate is set at 115200.
