** An instance of this class, like its parent, models a locking device that
** can be either open or closed; to open it requires that a prescribed 
** sequence of digits be entered on its keypad.  An instance of this class
** differs from an instance of its parent in that
** (1) its secret code can be replaced via a call to replaceCode()
** (2) digits entered on the keypad while the lock is open are ignored.
