Kernel::ConstructPerpendicularDirection_2

A model for this must provide:

Kernel::Direction_2 fo.operator() ( Kernel::Direction_2 d, Orientation o)
introduces a direction orthogonal to d. If o is CLOCKWISE, d is rotated clockwise; if o is COUNTERCLOCKWISE, d is rotated counterclockwise.
Precondition: o is not COLLINEAR.
