## Operations

A model of this concept must provide:
Kernel::Vector_2 | operator() (const Kernel::Point_2 &a, const Kernel::Point_2 &b)
| introduces the vector `b-a`.
Kernel::Vector_2 | operator() (const Origin &o, const Kernel::Point_2 &b)
| introduces the vector `b`.
Kernel::Vector_2 | operator() (const Kernel::Point_2 &a, const Origin &o)
| introduces the vector `-a`.
Kernel::Vector_2 | operator() (const Kernel::Segment_2 &s)
| introduces the vector `s.target()-s.source()`.
Kernel::Vector_2 | operator() (const Kernel::Ray_2 &r)
| introduces a vector having the same direction as `r`.
Kernel::Vector_2 | operator() (const Kernel::Line_2 &l)
| introduces a vector having the same direction as `l`.
Kernel::Vector_2 | operator() (const Null_vector &NULL_VECTOR)
| introduces a null vector .
