template<class T>
bool	is_truth_suppressed_pileup (const T &p)
	Method to establish if a particle (or barcode) corresponds to truth-suppressed pile-up.
template<class T>
bool	no_truth_link (const T &p)
	Method to establish if a if the object is linked to something which was never saved to the HepMC Truth - for example particle was too low energy to be recorded.
template<class T>
bool	ignoreTruthLink (const T &p, bool vetoPileUp)
	Helper function for SDO creation in PileUpTools.
template<class T>
bool	is_simulation_particle (const T &p)
	Method to establish if a particle (or barcode) was created during the simulation (only to be used in legacy TP converters).
template<class T>
bool	is_sim_secondary (const T &p)
	Method to establish if a particle (or barcode) is a new seondary created during the simulation (only to be used in legacy TP converters).
template<class T>
int	generations (const T &p)
	Method to return how many interactions a particle has undergone during simulation (only to be used in legacy TP converters).
template<class T>
bool	is_simulation_vertex (const T &v)
	Method to establish if the vertex was created during simulation (only to be used in legacy TP converters).
template<class T1, class T2>
bool	is_same_generator_particle (const T1 &p1, const T2 &p2)
	Method to establish if two particles in the GenEvent actually represent the same generated particle.
template<class T1, class T2>
bool	is_same_object (const T1 &p1, const T2 &p2)
	Method to establish if two particles/vertices in the GenEvent actually represent the same generated particle.
template<class T1, class T2>
