inherits Intersection from IntRes2d
---Purpose: Generic algorithm to intersect a conic from gp and
-- a parametric curve. This class uses the class
-- IConicTool from IntCurve, and Domain from
-- IntCurve.
--
-- The template class for the PCurveTool is given in
-- the package IntCurve (CurveTool).
--
-- The methods used to know the result of the
-- intersection are inherited from the class
-- Intersection from IntRes2d.
--
-- Note: The exception ConstructionError is raised in
-- constructors or in Perform methods when a domain
-- (Domain from IntRes2d) is not correct, i-e when a
-- Circle (Circ2d from gp) or an Ellipse (i-e Elips2d
-- from gp) do not have a closed domain (use the
-- SetEquivalentParameters for a domain on a circle
-- or an ellipse) or the domain of the ThePCurve is
-- not bounded (HasFirstPoint() && HasLastPoint()
-- return True.)
