/*! \brief The class of dual 2-dimensional combinatorial maps:
 *  set of oriented faces pairwise sewed by an adjacency relation.
 *  A dual 2-map represents close or open oriented 2-manifolds (surfaces).
 *  - A dual 2-map is made of darts linked by the phi1 permutation
 * 	and/or the phi2 one-to-one relation.
 *  - In this class darts are interpreted as oriented edges.
 *  - The phi1 relation defines oriented faces (see Map1)
 *  and faces may have arbitrary size (degenerated faces are accepted).
 *  - The phi2 relation links oriented faces along oriented edges.
 *  A set of phi2-linked faces represents a surface 
 *  - Edges that have no phi2-link are border edges. If there exists
 *  such edges the map is open.
 *  - When every edge is phi2-linked, the map is closed. In this case
 *  some optimizations are enabled that speed up the processing of vertices.
