    /**
    @brief
        The EventMultiTrigger class is the equivalent of the EventTrigger class for MultiTriggers.
        Consequentially what it does is it provides a way to have a MultiTrigger triggered by any kinds of events.
        Events that are not caused by a MultiTrigger or by a MultiTrigger with an originator that is no target of this EventMultiTrigger are broadcasted to all entities that are the target of this EventMultitrigger. Events that are caused by MultiTriggers with an originator that is a target of this EventMultiTrigger just trigger the EventMultiTrigger for the originator that caused the MultiTrigger to trigger. Thus showing the equivalent behavior to the EventTrigger.

        Example:
        @code
        <EventMultiTrigger invert="true">
            <events>
                <trigger>
                    <MultiTrigger ... />
                    <EventListener ... />
                </trigger>
            </events>
        </EventMultiTrigger>
        @endcode
    @see MultiTrigger.h
        For more information on MultiTriggers.
