-/** N5110 Class
-@brief Library for interfacing with Nokia 5110 LCD display (https://www.sparkfun.com/products/10168) using the hardware SPI on the mbed.
-@brief The display is powered from a GPIO pin meaning it can be controlled via software. The LED backlight is also software-controllable (via PWM pin).
-@brief Can print characters and strings to the display using the included 5x7 font.
-@brief The library also implements a screen buffer so that individual pixels on the display (84 x 48) can be set, cleared and read.
-@brief The library can print primitive shapes (lines, circles, rectangles)
-@brief Acknowledgements to Chris Yan's Nokia_5110 Library.
