## Definition

Refines
  `AdaptableUnaryFunction`

  `Kernel::ConstructCrossProductVector_3`

## Operations
A model of this concept must provide:
Kernel::Vector_3 | operator() (const Kernel::Plane_3 &p)
| returns a vector that is orthogonal to the plane `p` and directed to the positive side of `p`.
Kernel::Vector_3 | operator() (const Kernel::Point_3 &p, const Kernel::Point_3 &q, const Kernel::Point_3 &r)
| returns a vector that is orthogonal to the plane defined by `Kernel::ConstructPlane_3()(p, q, r)` and directed to the positive side of this plane.
