	You should implement this to return `f(x)`

virtual bool	provides_coeff () const
	does this functor directly provide sum coefficients? or only function values?

virtual bool	screened (const Vector< double, NDIM > &c1, const Vector< double, NDIM > &c2) const
	Can we screen this function based on the bounding box information?

void	set_length_scale (double lo)
	adapt the special level to resolve the smallest length scale

virtual Level	special_level () const
	Override this to change the minimum level of refinement at special points (default is 6)

virtual bool	supports_vectorized () const
	Does the interface support a vectorized operator()?

virtual coeffT	values (const keyT &key, const Tensor< double > &tensor) const
