Detailed Description

Generate pile up collisions based on beam parameter If set_embedding_id(i) with a negative number or 0, the pile up event will be inserted with increasing positive embedding_id. This is the default operation mode. If set_embedding_id(i) with a positive number, the pile up event will be inserted with increasing positive embedding_id. This would be a strange way to use pile up.
