## Definition

Refines
  `AdaptableQuaternaryFunction`

## Operations
A model of this concept must provide:
Comparison_result | operator() (const Kernel::Point_2 &p, const Kernel::Point_2 &q, const Kernel::Point_2 &r, const Kernel::Point_2 &s)
| compares the signed distance of `r` and `s` to the directed line through `p` and `q`.
Comparison_result | operator() (const Kernel::Line_2 &l, const Kernel::Point_2 &r, const Kernel::Point_2 &s)
| compares the signed distance of `r` and `s` to the directed line `l`.
