Environnement used to symmetrise zones<p>
This class build symmetry specific informations needed to know how transform tiles when a zone is symmetrise.<p>
There is two states for a tile : Regular or Goofy. If the tile is regular, it doesn't need specific transformation when the zone is symmetrise. If the tile is goofy, the tile must be rotate by 180deg more to be correct.<p>
