Vector product in Point3.cc

[Philippe Marguinaud]

I would like to add a vector product method to Point3.cc :

Something like :

    static Point3 cross (const Point3 & p1, const Point3 & p2) 
    {   
      return Point3 
      (   
        p1[YY] * p2[ZZ] - p1[ZZ] * p2[YY],
        p1[ZZ] * p2[XX] - p1[XX] * p2[ZZ],
        p1[XX] * p2[YY] - p1[YY] * p2[XX] 
      );  
    }   

May I submit a branch on github ?
