Script interface for the TriggerModule of a Particle System.
This module is useful for killing particles when they touch a set of collision
      shapes, or for calling a script command to let you apply custom particle behaviors when the trigger is activated.
    The example code for MonoBehaviour.OnParticleTrigger shows how the callback type action works.
