## Kernel::CollinearHasOn_2

A model for this must provide:

bool | fo.operator() ( Kernel::Ray_2 r, Kernel::Point_2 p)
|  | checks if point p is on r. Precondition: p is on the supporting line of r.

bool

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

|  | checks if point p is on s. Precondition: p is on the supporting line of s.
