Operations

A model of this concept must provide:

Kernel::Vector_3 operator() (const Kernel::Plane_3 &h, int index)
 when index == 1, returns a vector b1 that is orthogonal to the normal n to plane h; when index == 2, returns a vector b2 that is orthogonal to n and b1 and such that for an arbitrary point p on the plane h, the orientation of p, p + b1, p + b2, and p + n is positive.
