class Bisec from Bisector
--- Purpose : Bisec provides the bisecting line between two elements
-- This line is trimed by a point <P> and it's contained in the domain
-- defined by the two vectors <V1>, <V2> and <Sense>.
--
-- Definition of the domain:
-- if <Sense> is true the bisecting line is contained in the sector
-- defined by <-V1> and <-V2> in the sense indirect.
-- if <Sense> is false the bisecting line is contained in the sector
-- defined by <-V1> and <-V2> in the sense direct.
--
-- <Tolerance> is used to define degenerate bisector.
-- if the bisector is an hyperbola and one of this radius is smaller
-- than <Tolerance>, the bisector is replaced by a line or semi_line
-- corresponding to one of hyperbola's axes.
-- if the bisector is a parabola on the focal length is smaller than
-- <Tolerance>, the bisector is replaced by a semi_line corresponding
-- to the axe of symetrie of the parabola.
-- if the bisector is an ellipse and the minor radius is smaller than
-- <Tolerance>, the bisector is replaced by a segment corresponding
-- to the great axe of the ellipse.
