## Operations
A model of this concept must provide:
bool | operator() (const Kernel::Circle_2 &c, const Kernel::Point_2 &p)
| returns true iff `p` lies on the boundary of `c`.
bool | operator() (const Kernel::Iso_rectangle_2 &i, const Kernel::Point_2 &p)
| returns true iff `p` lies on the boundary of `i`.
bool | operator() (const Kernel::Triangle_2 &t, const Kernel::Point_2 &p)
| returns true iff `p` lies on the boundary of `t`.
