+Jonathan Valvano, 7/18/2013
+See BmpConvert.cpp for how it works
+1) Create a bmp file
+   width less than or equal to 128 pixels
+   height less than or equal 160 pixels
+   save the image as a 24-bit bmp file
+   store in same directory as BmpConvert16.exe
+2) Execute BmpConvert16.exe
+   Type the image name 
+   E.g., if the file is horse.bmp, then type horse
+3) Open the corresponding txt file, select all, copy
+4) Open uVision compiler
+   paste new image as a data constant
+5) Draw the image by calling ST7735_DrawBitmap
+   E.g., center a 120x160 image
+         ST7735_DrawBitmap(4, 159, Horse, 120, 160);
