	Initializes the framework. Note: The curve on which the local properties are computed is defined using one of the following functions: Perform, PerformCurExt or PerformInf.
void	Perform (const Handle< Geom2d_Curve > &C)
	For the curve C, Computes both the inflection points and the maximum and minimum curvatures.
void	PerformCurExt (const Handle< Geom2d_Curve > &C)
	For the curve C, Computes the locals extremas of curvature.
void	PerformInf (const Handle< Geom2d_Curve > &C)
	For the curve C, Computes the inflections. After computation, the following functions can be used:
Standard_Boolean	IsDone () const
	True if the solutions are found.

Detailed Description

• the maximum and minimum curvatures
  
• the inflection points.
  A CurAndInf2d object provides the framework for:
  
• defining the curve to be analyzed
  
• implementing the computation algorithms
  
• consulting the results.

• IsDone to check if the computation was successful
  
• NbPoints to obtain the number of computed particular points
  
• Parameter to obtain the parameter on the curve for
  each particular point
  
• Type to check if the point is an inflection point or an
  extremum of curvature of the curve C.
  Warning
  These functions can be used to analyze a series of
  curves, however it is necessary to clear the table of
  results between each computation.
