/* ncTrigger class is responsible for the legacy trigger architecture.
   In the future, ncEntity can be configured so that legacy
   triggers can be disabled. That's why this class is separate from ncIO.
 
   This is a very low-level class. You're never meant to use this.
   Use ncEntity as a basis for your classes.
