      • execute

        public void execute​(NanoDBServer server)
             throws ExecutionException
        This method really doesn't do anything, and it isn't intended to be called. The server looks for this command when commands are being executed, and handles it separately.
        Specified by:
        execute in class Command
        Throws:
        ExecutionException - if an issue occurs during command execution
        Code Review:
        (Donnie) We could actually have this command operate on the server now that we pass it in... Need to think about this.
