-//------------------------- Purpose : -----------------------------------
-//- This function determines the orientation similarity of two planes.
-// Each plane is described by two vectors.
-//------------------------- Parameters : --------------------------------
-//- <refA> : - type : vector 3D (double)
-//- <refB> : - type : vector 3D (double)
-// - Description of the first plane
-//- <ori1> : - type : vector 3D (double)
-//- <ori2> : - type : vector 3D (double)
-// - Description of the second plane
-//------------------------- Return : ------------------------------------
-// double : 0 if the planes are perpendicular. While the difference of
-// the orientation between the planes are big more enlarge is
-// the criterion.
-//------------------------- Other : -------------------------------------
-// The calculus is based with vectors normalice
