class BisectingLocus from BRepMAT2d
---Purpose : BisectingLocus generates and contains the Bisecting_Locus
-- of a set of lines from Geom2d, defined by .
--
-- If the set of lines contains closed lines:
-- ------------------------------------------
-- These lines cut the plane in areas.
-- One map can be computed for each area.
--
-- Bisecting locus computes a map in an area.
-- The area is defined by a side (MAT_Left,MAT_Right)
-- on one of the closed lines.
--
-- If the set of lines contains only open lines:
-- --------------------------------------------
-- the map recovers all the plane.
--
-- Warning: Assume the orientation of the closed lines are
-- compatible.
--
-- Assume the explo contains only lines located in the
-- area where the bisecting locus will be computed.
--
-- Assume a line don't cross itself or an other line.
--
-- Remark:
-- the curves coming from the explorer can be
-- decomposed in different parts. It the case for the
-- curves other than circles or lines.
--
-- The map of bisecting locus is described by a graph.
-- - The BasicsElements correspond to elements on
-- the figure described by the Explorer from BRepMAT2d.
-- - The Arcs correspond to the bisectors.
-- - The Nodes are the extremities of the arcs.
