Nokia 5100 LCD Example Code
   Graphics driver and PCD8544 interface code for SparkFun's
   84x48 Graphic LCD.
   Original Source code

  This stuff could all be put into a library, but we wanted to
  leave it all in one sketch to keep it as transparent as possible.

  Hardware: (Note most of these pins can be swapped)
    Graphic LCD Pin ---------- Arduino Pin
       1-VCC       ----------------  5V
       2-GND       ----------------  GND
       3-SCE       ----------------  7
       4-RST       ----------------  6
       5-D/C       ----------------  5
       6-DN(MOSI)  ----------------  11
       7-SCLK      ----------------  13
       8-LED       - 330 Ohm res --  9
   The SCLK, DN(MOSI), must remain where they are, but the other 
   pins can be swapped. The LED pin should remain a PWM-capable
   pin. Don't forget to stick a current-limiting resistor in line
   between the LCD's LED pin and Arduino pin 9!

    // setPixel takes 2 to 3 parameters. The first two params
    // are x and y variables. The third optional variable is
    // a "color" boolean. 1 for black, 0 for white.

    // the color set to black.

    // to actually make the display draw something new.

    //invertDisplay(); // This will swap all bits in our display

    // setLine(x0, y0, x1, y1, bw) takes five variables. The

  // x0, y0, x1, and y0 are the two diagonal corner coordinates
  // fill is a boolean, which determines if the rectangle is
