## Kernel::ComputeArea_2

A model for this must provide:

Kernel::FT

fo.operator() ( | Kernel::Point_2 p, Kernel::Point_2 q, Kernel::Point_2 r)

|  | returns the signed area of the triangle defined by the points p, q and r.
Kernel::FT | fo.operator() ( Kernel::Iso_rectangle_2 r)
|  | returns the area of r.
Kernel::FT | fo.operator() ( Kernel::Triangle_2 t)
|  | returns the signed area of t.
