// -------------------------------------------------------------------------
// This code is an implementation of the well known quad edge (QE) data
// structure in the ITK library. Although the original QE can handle non
// orientable 2-manifolds and its dual and its mirror, this implementation
// is specifically dedicated to handle orientable 2-manifolds along with
// their dual.
