/*
write_to_end_log() takes an int argument because this **WILL** run until the battery
expires, and the machine shuts down. Because of this, we want to make sure we don't
lose data because it was trying to write to a file during power failure. This is for
testing the RPi's battery consumption to get real-world data. It's MEANT to go until
battery failure, and this is only for testing purposes. Therefore, we will write to
two files, and alternate between writing to them, just in case the power should fail
DURING the writing process. We only need to know the startup time and the time of the
last file write, so we keep one startup-log file, and two end-log files, just in case.

/* This is a simple test, designed to make sure the MEGA 2560 is talking to your GPS EM-506 unit.
For this program, we are assuming you're using a MEGA 2560 and the "naked GPS" breakout board with
a bi-directional level shifter to interface the 3.3V pins of the GPS with the 5V pins of the MEGA.
Wiring should be done as follows:
GPS Pin 1: GND
GPS Pin 2: VCC +5V (this is not a mistake. The GPS unit itself has a voltage regulator that can handle 5V,
                    but the serial pins (TX RX) must be at 3.3V)
GPS Pin 3: RX pin (goes to TX1 Digital Pin 18 on MEGA via level shifter)
GPS Pin 4: TX pin (goes to RX1 Digital Pin 19 on MEGA via level shifter)
GPS Pin 5: GND
