\ccDefinition

The class \ccRefName\ is a model for the \ccc{Bitangent} concept. \ccc{Disk} is
the disk type.

Partial specializations of \ccRefName\ are given for the types
\ccc{CGAL::Point_2<R>}, \ccc{CGAL::Segment_2<R>}, \ccc{CGAL::Circle_2<R>} and
\ccc{CGAL::Polygon_2<R>}.
Adding a partial specialization is done by inheriting from the class
\ccc{CGAL::Bitangent_base<Disk>} and implementing the constructors described in
the \ccc{Bitangent} concept.
