/**
* \file
*
* Interface for draw font on LCD.

*/
/**
*
* \section Purpose
*
* The font.h files declares a font structure and a LCDD_DrawChar function
* that must be implemented by a font definition file to be used with the
* LCDD_DrawString method of draw.h.
*
* The font10x14.c implements the necessary variable and function for a 10x14
* font.
*
* \section Usage
*
* -# Declare a gFont global variable with the necessary Font information.
* -# Implement an LCDD_DrawChar function which displays the specified
* character on the LCD.
* -# Use the LCDD_DrawString method defined in draw.h to display a complete
* string.
