deferred class 

     Bisec from GccInt

inherits TShared from MMgt

     	---Purpose: 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.
