	jL (const Grid &r_grid, const Grid &q_grid, std::size_t max_l, bool subtract_one=false)
	Contruction takes radial grid, a q grid, and a maximum L. Fills lookup table.

	jL (const jL &other)
	Constructing from existing operator: copies JL table - faster. Can copy from a jL of different type (g0,g5 etc)

jL &	operator= (const jL &)=delete

std::size_t	L () const
	Current value of L (should = rank)

std::size_t	max_L () const
	Maximum L value in table.

DiracSpinor	radial_rhs (const int kappa_a, const DiracSpinor &Fb) const override
	radial_int = Fa * radial_rhs(a, Fb) (a needed for angular factor)

virtual double	radialIntegral (const DiracSpinor &Fa, const DiracSpinor &Fb) const override final
	Defined via <a\|\|h\|\|b> = angularF(a,b) * radialIntegral(a,b) (Note: if radial_rhs is overridden, then radialIntegral must also be_.

double	rme (const DiracSpinor &a, const DiracSpinor &b, std::size_t L, double q) const
	Directly calculate reduced matrix element without needing to call set_L_q - this is thread safe.

bool	is_zero (const DiracSpinor &a, const DiracSpinor &b, std::size_t L) const
	Checks if specific ME is zero (when not useing set_L_q)

std::string	units () const override final
	Returns units of operator (usually au, may be MHz, etc.)
