/*********************************************************************
This is a library for our Monochrome OLEDs based on SSD1306 drivers
Pick one up today in the adafruit shop!
------> http://www.adafruit.com/category/63_98
These displays use SPI to communicate, 4 or 5 pins are required to
interface
Adafruit invests time and resources providing this open source code,
please support Adafruit and open-source hardware by purchasing
products from Adafruit!

02/18/2013 Charles-Henri Hallard (http://hallard.me)
Modified for compiling and use on Raspberry ArduiPi Board
LCD size and connection are now passed as arguments on
the command line (no more #define on compilation needed)
