struct	get_indices
	return a list of indices that correspond to a given MC decay. The list contains the index of the mother, followed by the indices of the daughters, in the order specified. If m_inclusiveDecay is true, the list of daughters is the minimum required for the mother's decay (otherwise, the list is the exact daughters required for the mother's decay). In case there are several such decays in the event, keep only the first one. More...
