/**
 * This is an observer class that is implemented by CLbtStrategy. This class

 * trigger fire events when suggested by Strategy Engine. When strategy engine
 * evaluates the trigger and updates the trigger fired status, trigger view 
 * reflects these changes in the container and upon successful completion of
 * the operation on container reports the trigger fire event to CLbtStrategy
 * which inturn notifies Server Logic
 *
