double	fastjet::dot_product (const PseudoJet &a, const PseudoJet &b)
bool	fastjet::have_same_momentum (const PseudoJet &jeta, const PseudoJet &jetb)
	returns true if the momenta of the two input jets are identical
PseudoJet	fastjet::PtYPhiM (double pt, double y, double phi, double m)
	return a pseudojet with the given pt, y, phi and mass
std::vector< PseudoJet >	fastjet::sorted_by_pt (const std::vector< PseudoJet > &jets)
	return a vector of jets sorted into decreasing transverse momentum
std::vector< PseudoJet >	fastjet::sorted_by_rapidity (const std::vector< PseudoJet > &jets)
	return a vector of jets sorted into increasing rapidity
std::vector< PseudoJet >	fastjet::sorted_by_E (const std::vector< PseudoJet > &jets)
	return a vector of jets sorted into decreasing energy
std::vector< PseudoJet >	fastjet::sorted_by_pz (const std::vector< PseudoJet > &jets)
	return a vector of jets sorted into increasing pz
void	fastjet::sort_indices (std::vector< int > &indices, const std::vector< double > &values)
	sort the indices so that values[indices[0->n-1]] is sorted into increasing order
template<class T >
std::vector< T >	fastjet::objects_sorted_by_values (const std::vector< T > &objects, const std::vector< double > &values)
	given a vector of values with a one-to-one correspondence with the vector of objects, sort objects into an order such that the associated values would be in increasing order (but don't actually touch the values vector in the process).
Variables
const double	fastjet::MaxRap = 1e5
	Used to protect against parton-level events where pt can be zero for some partons, giving rapidity=infinity.
