 //! The deferred class GccInt_Bisec is the root class for
 //! elementary bisecting loci between two simple geometric
 //! objects (i.e. circles, lines or points).
 //! Bisecting loci between two geometric objects are such
 //! that each of their points is at the same distance from the
 //! two geometric objects. It is typically a curve, such as a
 //! line, circle or conic.
 //! Generally there is more than one elementary object
 //! which is the solution to a bisecting loci problem: each
 //! solution is described with one elementary bisecting
 //! locus. For example, the bisectors of two secant straight
 //! lines are two perpendicular straight lines.
 //! The GccInt package provides concrete implementations
 //! of the following elementary derived bisecting loci:
 //! -   lines, circles, ellipses, hyperbolas and parabolas, and
 //! -   points (not used in this context).
 //! The GccAna package provides numerous algorithms for
 //! computing the bisecting loci between circles, lines or
 //! points, whose solutions are these types of elementary bisecting locus.
