/// \unit
///
/// !!!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.
///
/// !!!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.
