// This implementation is designed to be #included ONLY ONCE in the .ino

// It will create a driver implemntation and a shim class implementation.
// This means that other classes can reference the shim without knowing

// SSD1306AsciiWire for I2C OLED driver with SSD1306 or SH1106 controllers;
// LiquidCrystal_I2C for I2C LCD driver for HD44780 with PCF8574 'backpack'.
