 * data & methods for error handling object
 *
 * Error handling will differ in different systems
 * depending upon the board, processor, and application
 * One may want to log errors to a non-volatile
 * store, blink lights, and print out a message.
 * If so, this is the place to put the methods that
 * initiate those activities.
 *
 * This version just provides a single error handling
 * routine which stores an error code in a variable
 * (to look at with a debugger) and then loops forever.
