package IntCurve

    ---Purpose: This package provides algorithmes to intersect 2D curves,
    --          with domains.
    --          
    --          class IntConicConic : Algorithm used to intersect 2 conics 
    --                                from gp with domains.
    --                                
    --          class IntConicCurveGen : Generic algorithm used to intersect 
    --                                   a conic from gp, and a parametrised
    --                                   curve.
    --                                   The parametrised Curve can 
    --                                   not be a Composite curve and 
    --                                   can not be a conic.

    --                                   curves. The resources on a curve are
    --                                   discribed in the class CurveTool.

    --          class UserIntConicCurveGen: Generic algorithm used to  
    --                                      intersect a Conic from gp 
    --                                      and a parametrised curve. 
    --                                      This curve can be either a  
    --                                      composite curve or a conic.
