 Calculates the distance between two hyperbolas.
The hyperbolas can be parallel or identical.

 Extrema_ExtElC (const gp_Hypr &C1, const gp_Parab &C2)
 Calculates the distance between a hyperbola and a
parabola.

 Extrema_ExtElC (const gp_Parab &C1, const gp_Parab &C2)
 Calculates the distance between two parabolas
The parabolas can be parallel or identical.

Standard_Boolean IsDone () const
 Returns True if the distances are found.

Standard_Boolean IsParallel () const
 Returns True if the two curves are parallel.

Standard_Integer NbExt () const
 Returns the number of extremum distances.

Standard_Real SquareDistance (const Standard_Integer N=1) const
 Returns the value of the Nth extremum square distance.

void Points (const Standard_Integer N, Extrema_POnCurv &P1, Extrema_POnCurv &P2) const
 Returns the points of the Nth extremum distance.
P1 is on the first curve, P2 on the second one.
