 *  \brief ANSI terminal special escape code macros.
 *
 *  \section Sec_Terminal_Dependencies Module Source Dependencies
 *  The following files must be built with any user project that uses this module:
 *    - None
 *
 *  \section Sec_Terminal_ModDescription Module Description
 *  Escape code macros for ANSI compliant text terminals.
 *
 *  \note If desired, the macro \c DISABLE_TERMINAL_CODES can be defined in the project makefile and passed to the GCC
 *        compiler via the -D switch to disable the terminal codes without modifying the source, for use with non
 *        compatible terminals (any terminal codes then equate to empty strings).
 *
 *  \section Sec_Terminal_ExampleUsage Example Usage
 *  The following snippet is an example of how this module may be used within a typical
 *  application.
 *
 *  \code
 *      printf("Normal String, "
 *             ESC_BOLD_ON "Bold String, "
 *             ESC_UNDERLINE_ON "Bold and Underlined String"
 *             ESC_RESET ESC_FG_BLUE ESC_BG_YELLOW "Normal Blue-on-Yellow String");
