package AppDef

    ---Purpose: This package describes all the classes needed to approximate 
    --          points in Bezier curves. It is used in the package 
    --          AppParCurves.
    --          The points of the same range for the approximation are 
    --          organised in MultiPointConstraints. These MultiPointConstraints
    --        
    --            are organized in a MultiLine.
    --          The corresponding result of a MultiLine approximation is
    --          a MultiCurve (set of Bezier curves) which has the same 
    --          structure as a MultiLine: The MultiCurve is a set of 
    --          MultiPoint.
    --          A point of a MultiLine can have many significations: the approximation curve
    --          can go through this point or not, can have a given tangency, or can 
    --          have a given curvature.
    --          Note: a CurvaturePoint is also a PassPoint and a TangencyPoint.
    --          A TangencyPoint is also a PassPoint.

is

class MultiPointConstraint;  
    ---Purpose: a MultiPointConstraint is a set of points which have the same range 
    -- in the MultiLine and the same constraints.


class MultiLine;
    ---Purpose: this is the organized set of points.

class MyLineTool;
    ---Purpose: example of MultiLine tool corresponding to the tools of the packages
    -- AppParCurves and Approx. For Approx, the tool will not addd points
    -- if the algorithms want some.
