## Kernel::HasOn_2

A model for this must provide:

bool | fo.operator() ( Kernel::Line_2 l, Kernel::Point_2 p)
|  | returns true iff p lies on l.
bool | fo.operator() ( Kernel::Ray_2 r, Kernel::Point_2 p)
|  | returns true iff p lies on r.

bool

fo.operator() ( | Kernel::Segment_2 s, Kernel::Point_2 p)

|  | returns true iff p lies on s.
