/** To generate a fatal compile-time error, you can use the pre-processor #error directive.
 *
 * @code
 * #error "That shouldn't have happened!"
 * @endcode
 *
 * If the compiler evaluates this line, it will report the error and stop the compile.
 *
 * For example, you could use this to check some user-defined compile-time variables:
 *
 * @code
 * #define NUM_PORTS 7
 * #if (NUM_PORTS > 4)
 *     #error "NUM_PORTS must be less than 4"
 * #endif
 * @endcode
 *
 * Reporting Run-Time Errors:
 * To generate a fatal run-time error, you can use the mbed error() function.
 *
 * @code
 * error("That shouldn't have happened!");
 * @endcode
 *
 * If the mbed running the program executes this function, it will print the
 * message via the USB serial port, and then die with the blue lights of death!
 *
 * The message can use printf-style formatting, so you can report variables in the
 * message too. For example, you could use this to check a run-time condition:
 *
 * @code
 * if(x >= 5) {
 *     error("expected x to be less than 5, but got %d", x);
 * }
 * #endcode
