+ Example of creating a file, reading a file, and reading the disk properties on OpenLog

+
+ This example reads the firmware version of the OpenLog without the need for a USB to serial connection.
+ The firmware version of your OpenLog is very helpful if you need tech support.
+ 
+ Connect the following OpenLog to Arduino:
+ RXI of OpenLog to pin 2 on the Arduino
+ TXO to 3
+ GRN to 4
+ VCC to 5V
+ GND to GND
+ 
+ This example code assumes the OpenLog is set to operate in default mode. This is 9600bps 
+ in NewLog mode, meaning OpenLog should power up and output '12<'. This code then sends the 
+ three escape characters and then sends the commands to bring up the help menu '?' and then
+ looks for the "OpenLog v4.0" text at the top of the menu. It will then print the version
+ # to the serial terminal.
+ 
+ This code assume OpenLog is in the default state of 9600bps with ASCII-26 as the esacape character.
+ If you're unsure, make sure the config.txt file contains the following: 9600,26,3,0
+ 
+ Be careful when sending commands to OpenLog. println() sends extra newline characters that 
+ cause problems with the command parser. v2.51 and above ignores \n commands so it should be easier to 
+ talk to on the command prompt level. This example code works with all OpenLog v2 and higher.
